Modified in this release: <ahref="ar-model.html">ar-model</a>, <a href="extrema.html">extrema</a>,<a href="nstep.html">nstep</a>, <a href="boxcount.html">boxcount</a>,<a href="lyap_spec.html">lyap_spec</a>, <ahref="recurr.html">recurr</a>, <a href="makenoise.html">makenoise</a>and <a href="rescale.html">rescale</a>.</li><li>To achieve consistency with the other programs I renamed someflags. The affected programs and flags are: <a href="d2.html">d2</a>flags <font color=red>-e to -r</font>, <font color=red>-E to -R</font>and therefore, <font color=red>-R to -E</font>, <ahref="av-d2.html">av-d2</a> flag <font color=red>-e to -E</font>,<a href="histogram.html">histogram</a> flag <font color=red>-e to-r</font> and <a href="boxcount.html">boxcount</a> flag <fontcolor=red>-e to -r</font> and <font color=red>-E to -R</font>.</li><li> I gave unique <a href="../../source_c/routines/tisean_cec.h">exitcodes</a> to all the exceptions in the routines. I'm pretty sureThomas will have doubts about the usefulness of this, but who knowswhat it is good for.</li><li>Again <a href="recurr.html">recurr</a>: It does no longer printthe diagonal terms. That was really nothing than a waste of discspace. Furthermore, it now uses a two-dimensional box assisted searchalgorithm. Should be a bit faster, therefore.</li><li><a href="makenoise.html">makenoise</a> has got a new flag <fontcolor=red>-0</font> which, if set, allows to produce random numberswithout reading any data.</li><li><a href="zeroth.html">zeroth</a> was replaced by the old <ahref="zeroth.html">mzeroth</a>. It got one newfunctionality. Depending on the Verbosity level it now prints theindividual forecast error for each component of each reference point.</li><li><a href="nstep.html">nstep</a> got a new flag <fontcolor=red>-0</font>. Setting this flag causes nstep to perform azeroth order fit instead of a local linear one.</li><li><a href="nstat_z.html">nstat_z</a> the flag <fontcolor=red>-S</font> was renamed <font color=red>-s</font> to beconsistent with the other programs.</li><li>The programs <a href="nstat_z.html">nstat_z</a>, <ahref="zeroth.html">zeroth</a>, <a href="onestep.html">onestep</a>and <a href="ll-ar.html">ll-ar</a> got a new flag <ahref="causality.html">-C</a>.</li><li>The program <a href="nrlazy.html">nrlazy</a> got a new verbositylevel. If this level is set the number of neighbors used for thecorrection is printed to the output file. If this number is 1, nocorrection was done.</li></ul><hr><h4 align=center>Bug Fixes</h4><ul><li>There was a slight inconsistency in the <ahref="xcor.html">xcor</a> man page. The page stated the output filecontains <x<sub>t</sub>*y<sub>t-d</sub>>, instead it is<x<sub>t</sub>*y<sub>t+d</sub>>. REMOVED (Thanks to Marioagain)</li><li><a href="d2.html">d2</a> crashed when the maximal dimension wasONE. FIXED. (Results for 'non crashing' cases were not influenced, atall)</li><li>There was a bug in <a href="mutual.html">mutual</a>, which couldlead to negative mutual information in case that the delay time waslong compared with the length of the time series. FIXED (Thanks toEckehard) </li><li>Though stated somewhere on this page, the output of <ahref="histogram.html">histogram</a> was not produced in such a waythat the integration over the whole data interval gave 1. Now itdoes.</li><li>I removed a lot of 'index out of range segmentation faults' in theprograms. (Thanks to a lot of people)</ul><hr><h4 align=center>New programs</h4><ul><li> <a href="sav_gol.html">sav_gol</a>: Performes a Savitzky-Golayfilter on, possibly multivariate, data to either clean the data or toget better estimates for their derivatives.</li><li><font color=red>Suggestions for further (not too specific)programs are welcome.</font></li></ul><hr><a href="#top">top</a> of the page.<hr><center><font size=4 color=blue><b><a name="tisean1.2">TISEAN_1.2 -> TISEAN_2.0</a></b></font></center><hr><h4 align=center>Changes</h4><ul><li>A new routine <a href="../../source_c/routines/exclude_interval.c">exclude_interval</a> was added to <ahref="routines.html">tsa.h</a>. It allows to exclude an interval ofindexes from a list of neighbors found.</li><li><a name="lyap_k"></a>When the parameter of <font color=red>-m</font> is larger thanthat of <font color=red>-M</font> in <a href="lyap_k.html">lyap_k</a>,now the <font color=red>-m</font> value is used. (Thanks to JensTimmer)</li><li>Furthermore, <a href="lyap_k.html">lyap_k</a> was rewritten in C.</li><li>The programs <font color=blue>delay, make_ps</font> wereremoved from the supported part of the package. In case you area fan of these programs, you'll find the sources and the html-files inthe directory <font color=blue>unsupported</font>. As thename says, there will be no support, what so ever, for theseprograms. Maybe <font color=blue>make_ps</font> will come back in alater version when it is useful for more people, not only for me.</li><li>The program <a href="histogram.html">histogram</a> was rewrittenin C. This means the package is now C++ free.</li><li>The program <a href="nrlazy.html">nrlazy</a> has an additionaloption <font color=red>-v</font> which allows to set the neighborhoodsize in units of the standard deviation of the data.</li><li>The program <a href="d2.html">d2</a> is now able to handle multivariatedata, also with mixed embeddings. Further, the default for the <fontcolor=red>-N</font> is now 1000 instead of all. To get all back, set thevalue to 0. Furthermore, columns 1 and 3 in the output files areinterchanged. The first column now contains the length scales in unitsof the data.</li><li>The program <a href="av-d2.html">av-d2</a> was changed in a waythat it is now able to handle the output of the files of the program. Since the natural unitsfor length scales are the default units now, the option <fontcolor=red>-r</font> was replaced by <font color=red>-e</font>.</li><li>Some of the messages of the programs were changed to avoid thatthey look like error messages. (Thanks to ChristianRödenbeck)</li><li>Two new routines to handle multivariate time series were added to<a href="routines.html">tsa.h</a>: <ahref="../../source_c/routines/make_multi_box.c">make_multi_box</a> and<a href="../../source_c/routines/find_multi_neighbors.c">find_multi_neighbors</a>.</li><li>To reduce the number of <i>segmentation faults</i> anotherroutine <ahref="../../source_c/routines/check_alloc.c">check_alloc</a> was addedto <a href="routines.html">tsa.h</a>.</li><li>A new flag <font color=red>-S</font> was added for the <ahref="zeroth.html">zeroth</a> program.</li><li>The <font color=red>-F</font> was replaced by <fontcolor=red>-c</font></li>.<li>To make the <font color=red>-c</font> and <fontcolor=red>-m</font> flags more flexible to use I changed the routine<ahref="../../source_c/routines/get_multi_series.c">get_multi_series</a>in <a href="routines.html">tsa.h</a>.</li><li>Now <a href="mutual.html">mutual</a> uses the standard norm forits output.</li><li>A new routine <ahref="../../source_c/routines/what_i_do.c">what_i_do</a> was added to<a href="routines.html">tsa.h</a>. Itdisplays kind of a welcome message when the program is started.</li><li>A new routine <ahref="../../source_c/routines/myfgets.c">myfgets</a> was added to <ahref="routines.html">tsa.h</a>. It handles loooong input lines.</li><li>A new flag <font color=red>-V</font> was added for allprograms. It allows to add an <a href=../general.html#verbosity>verbosity level</a> like in Thomas'programs. See the corresponding help pages for more info. According tothis change, I had to modify the routine <fontcolor=blue>get_series</font> and <font color=blue>get_series</font> in<a href="routines.html">tsa.h</a>.</li><li><a href="lyap_spec.html">lyap_spec</a> is now able to handledelays other than 1.</li></ul><hr><h4 align=center>Bug Fixes</h4><ul><li><a name="ll-ar"></a>When using the routines <a href="ll-ar.html">ll-ar</a>, <ahref="onestep.html">onestep</a> and <a href="zeroth.html">zeroth</a>with the <font color=red>-s</font> flag set to a value larger than 1the points mapped into the interval [actual point,actual point + valueof -s] were not excluded from the neighborhood. This caused causalityproblems especially for oversampled flow data, which could result ina severe underestimation of the forecast errors. FIXED (Thanks to MarioRagwitz and Holger)</li><li>The <font color=red>-r</font> flag in <ahref="xzero.html">xzero</a> was buggy. When used, the result wasusually (depending on the architecture) a <font color=blue>floatingexecption</font>. (Thanks to Mario Ragwitz)</li></ul><hr><h4 align=center>New programs</h4><ul><li><a name="mzeroth"></a><a href="zeroth.html">mzeroth</a>: Estimates the forecast errors fora multicomponent time series using a zeroth order model.</li><li><a name="nstat_z"></a><a href="nstat_z.html">nstat_z</a>: Takes a scalar time series,⌨️ 快捷键说明
