     uses the LOG case of arr_func in computing powers.

filter
     this program has been removed and replaced by  filter2,
     which  was  introduced  in  the  previous ESPS release.
     Filter has been removed (it is unstable) and  the  name
     filter is now linked to filter2.

find_ep
     bugs fixed: (1) the filename in the common file was not
     updated  if the -w option was in effect; (2) one of the
     debugging messages produced with the -x  option  showed
     garbage  for the output file name; (3) if the -n option
     was used with no filename in common, the program  would
     produce  a  core  dump,  rather  than an error message,
     before  exiting.    The   150   ms   lower   limit   on
     "silence_req",  the  argument  of  the -s option, is no
     longer enforced; it is just stated as a recommend lower
     limit  in  the  manual  entry.  A missing -b option was
     added to the Synopsis in the manual entry.

image
     a bug in the image program was fixed that  caused  core
     dumps  when  a debug level of 2 or higher was specified
     with the -x option.

mbuttons
     If -c is specified, a set  of  exclusive  panel  choice
     buttons is used for each olwm submenu instead of a menu
     button with a pull-down menu.  By  default  the  choice
     buttons  are  laid out vertically.  If -h is used, they
     are laid out horizontally.

mbuttons
     added -Q option to allow arbitrary label for quit  but-
     ton;  added -l option to allow command for execution on
     exit via quit button.

mu2esps
     this program  can  now  handle  SUNOS  4.1  audio  file
     headers.

plot3d
     Two plot3d bugs were fixed:  moving the  box  with  the
     mouse  with  no  data  loaded  could cause a core dump;
     sometimes the 3d cursors were drawn in the wrong  rela-
     tion to the mouse position.   Major improvement is that
     hardcopy output of the plot is now possible, in  either
     PostScript  or  PCL.   A print setup panel is available
     for selecting output type, scaling, and output device.

plotfield
     A bug was fixed in the  plotfield  script  that  caused
     incorrect processing of command-line arguments when the
     text argument of the -t option contained blanks.

sfconvert
     changed the default value of sfwin_len in  the  default
     parameter  file  to  a  more  reasonable  value  of .01
     (seconds).

sgram
     reversed the sense of the -z option  so  that  warnings
     about zero power in frames are off by default.

splay
     a bug was fixed with caused the -a to  have  no  effect
     unless  the  -b option was used also.  And if -a and -b
     are both used, the -b option has no effect.

srecord
     modified to require an output file,  or  -  to  specify
     standard output.

tofspec
     The tofspec program can now produce FEA_SPEC  files  in
     "ARB_FIXED"  format---frequency  values  are not neces-
     sarily uniformly spaced and are given  by  an  explicit
     list  in  the header.  The frequencies may be specified










ESPS Version 5.0 Release Notes                        page 7


     by a command-line option or a parameter-file entry.

vqasc
     memory leak fixed.

vqdesasc
     added -l option as was added to vqasc in  version  4.2.
     This  option  is  to  allow specification of input line
     length to override compiled in default.

wmse_filt
     a FIR design program by minimum mean square error  cri-
     teria,  no  longer  prompts user for design parameters.
     It now supports standard ESPS parameter  file  process-
     ing,  which  can  be  used  with  xeparam(1-ESPS),  and
     eparam(1-ESPS).

xfft xfft was changed to permit a -c option; a new parameter
     file  PWfftc  was  created  to  facilitate  taking fft-
     spectrograms of complex sampled data.

5.  NEW AND CHANGED LIBRARY FUNCTIONS

arr_func
     modified to handle additional function, exp10,  inverse
     of log10.  Use by feafunc program.

arr_op
     This a new library function for performing  element-by-
     element  arithmetic  operations on arrays of any of the
     ESPS numeric types.  The currently supported operations
     are  addition,  subtraction,  multiplication, division,
     forming a complex number from its  real  and  imaginary
     parts, and raising a given number to a given power.

exv_bbox
     exv_bbox was extended to support exclusive panel_choice
     buttons  for  submenus  instead  of  menu  buttons with
     pull-down menus.  There are two new items in the param-
     eter structure (typedef bbox_par):
       int button_choice;            /* if true, show submenus as panel choice
                                        items instead of button menus */
       int choice_horizontal;        /* if true, panel choice items are
                                        displayed horizontally */

exv_bbox
     added the following parameters for allowing the user to
     put  an  arbitrary label on the QUIT button and to exe-
     cute an arbitrary function when it is pressed
               char *quit_label;     /* if non-NULL, name for QUIT button */
               char *quit_data;      /* QUIT button data string */
               void (*quit_data_proc)(); /* execution function for QUIT data data */
     these changes are needed in order to support  analogous

     changes to fbuttons and mbuttons

get_genhd_coded
     A bug was fixed in the library function get_genhd_coded
     for  items  with  more  than  one element, the returned
     value consisted of repetitions of the first element.

matinv
     a bug in the determinant functions, determ and determ_d
     was  fixed:  they would allocate memory and not free it
     before returning.  The  problem  was  apparent  in  the
     operation  of  the  classify  program, which would fail
     with a memory allocation failure after classifying some
     number  of records (a number depending on the number of
     classes and the number of features used for classifica-
     tion).

read_header
     a bug was fixed that could cause a program to fail when
     reading a FEA_SPEC file with frequency format ARB_FIXED
     by unnecessarily demanding the presence of a sf generic
     header  item.   read_header was also modified to handle
     version 1.7a of Sphere headers.

waves_show_sd
     this new library function allows  user  to  display  an
     array  of  data  by  a  simple call and have the result
     displayed in an xwaves window if xwaves is  running  in
     server mode.

6.  THE PUB DIRECTORY

The directory $ESPS_BASE/pub contains full-source copies  of
certain  relevant and useful public domain programs. You are
free to use them and pass them on in any  manner  consistent
with  restrictions  stated  by  their authors.  This release
contains these programs:

ghostscript
     This is a GNU implementation of PostScript.   It can be
     used to display PostScript files on the screen for cer-
     tain PostScript translations.  We have included  it  to
     make  the script ps2epsi available.  This script (which
     uses ghostscript will take the PostScript file from the
     new  print  option  on xwaves and plot3d and generate a
     new file including a preview image.  This allows a  low
     resolution  image of the PostScript file to be shown on
     the screen when the file is imported into programs such
     as FrameMaker.

tpipe
     This is a utility that splits a unix pipeline into  two
     pipelines.   Stated differently, the output of one pipe










ESPS Version 5.0 Release Notes                        page 9


     can provide the intput to two others.  tpipe was  writ-
     ten by David B. Rosen of Boston University.

xgrabsc
     A utility that allows you to grab arbitrary portions of
     the  screen and output them in Postscript or many other
     formats.  xgrabsc was written by Bruce Schuchardt.

tek2ps
     Written by Michael  Fischbein,  this  program  converts
     tektronix graphics codes into Postscript.  This is used
     by some of our plotting programs.

shellforms
     This is a utility to build  and  edit  forms.   It  was
     written by Paul Lew.

ghostscript
     This is a GNU  implementation  of  PostScript.   It  is
     included  here  because  it  includes a script that can
     process a PostScript file as output by  the  new  print
     graphics  feature  of ESPS and xwaves and add a preview
     image.  This script is ps2epsi.   The  particular  ver-
     sion of this script in our bin directory has been modi-
     fied to refer the the ghostscript library  in  our  pub
     directory.    If you desire to use the general features
     of ghostscript, you will have to install  it  from  the
     source.
