Revision history for Perl extension Math::FFT.
1.28 Sat Sep 03 2005
- bump version so PAUSE ignores deleted 1.27 package
0.28 Sun Aug 28 2005
- fix version mistake in META.yml
0.27 Sun Aug 28 2005
- add method to calculate root mean square of data (suggested
by Robert Hiller)
- in calculating the power spectrum, use same logic for
segments = 1 as is currently done for segments > 1 when
"number" is specified (suggested by Robert Hiller)
- in calculating the power spectrum, check if data size
is an integral power of 2 if segments is not specified
or if segments = 1 and "number" is not specified
- in the spectrum method, change the name of the "hamm" window
function to "hann" (suggested by Robert Hiller). For
backwards compatibility, "hamm" is still supported.
- in the pod for the spctrm method, clarify how options
are to be passed in (suggested by Robert Hiller)
0.26 Sat Dec 04 2004
- include "arrays.h" in FFT.xs (required for some platforms)
(thanks to Doug Shubert)
0.25 Thu Dec 28 2000
- implement the routines of arrays.c of PGPLOT to pass
arrays to and from C
- added methods to calculate correlation, convolution
and deconvolution, and power spectrum
- added some simple statistical methods
0.15 Tue Dec 5 2000
- original version; created by h2xs 1.20 with options
-n Math::FFT
