\fBESPS 3.3b Release Notes\fP

Document version: 1.2 5/18/89
.sh 1 "Introduction"
.lp
This document provides notes relevant to release 3.3b of ESPS.  Please
read this document and the Installation Instructions completely before
installing this release of ESPS.  This note documents changes to ESPS
since the revisions 3.3 and 3.3a.  Please read the 3.3 and 3.3a
release notes first.
.sh 1 "Differences Between 3.3a and 3.3b
.lp
Please duplicate this section and make it available to all current users of
ESPS.  This information is needed by others than just the ESPS
installer.  Differences that affect the \fIwaves\fP+ standalone 
products are marked with an asterisk (\fIwaves+\fP standalone 
includes a subset of ESPS).  
.sh 2 "Bug Fixes"
.ip (1)
The \fIcopysps\fP (1\-\s-1ESPS\s+1) man page stated incorrectly that
\fIcopysps\fP does not work with SD files.  In fact it does.  The man
page was changed to describe the supported behavior.  A (Sun only) bug
that caused core dumps when copying entire SD files was fixed.
.ip (2)
\fIMlplot\fP (1\-\s-1ESPS\s+1) and \fIgenplot\fP (1\-\s-1ESPS\s+1)
were changed to fix a bug that caused a core dump when passed an
invalid data range.
.ip (3)
The Masscomp \fIxmcd\fP (1\-\s-1ESPS\s+1) binary was fixed to handle 
icons properly.  
.ip (4)*
The \fB-E\fP option on \fIsgram\fP (1\-\s-1ESPS\s+1) was being
ignored.  Also, the generic header item "pre_emphasis" was not being 
written to the output file.  These both have been fixed.  
.ip (5)*
The \fB-S\fP option on \fIaddfeahd\fP (1\-\s-1ESPS\s+1) has been fixed
to work properly.  
.sh 2 "Other Changes"
.ip (1)
The new program \fImergefea\fP (1\-\s-1ESPS\s+1) was added.  This
merges two FEA files so that output records contain fields from both.
For an example of its use, see the \fIratios\fP demo (next item).  
.ip (2)
A new demo was added to the ESPS demo directory to show how ESPS tools
can be combined to compute the ratios of power (or log power) in
different frequency bands for a sequence of sampled data frames, with
the results placed in a FEA file.  The script \fIratios.demo\fP sets
up the demo.  Power ratios or log power ratios are then computed
respectively using \fIratios\fP or \fIlogratios\fP.  The README file
in the demo directory has been revised to describe the new demo.  
.ip (3)
The new program \fIfeafunc\fP (1\-\s-1ESPS\s+1) was added.
\fIFeafunc\fP accepts a FEA file containing arbitrary fields.  It
produces a FEA file with records that are copies of the input records
plus an additional field containing the results of applying the
functional form \fIg*F(element) + d\fP to each element of a selected
input field, where \fIg\fP is a multiplicative constant, \fIF\fP is a
single-valued scalar function (\fIlog, ln, sqrt, abs, exp\fP), and
\fId\fP is an additive constant.
.ip (4)
A new library routine \fIcopy_genhd_uniq\fP (3\-\s-1ESPS\s+1) was
added.  This copies generic header items from one header to another,
but generates unique names in the case of conflicts.  (The routine
\fIcopy_genhd\fP overwrites existing items in the case of duplicate
names.)
