Maxima 5.19 change log
- Compiled 2009-08-xx
+ Compiled 2009-08-09
Backwards-incompatible changes:
+ * eigenvector: greater detail in return value
+
+ * package fft:
+ renamed ift to inverse_fft
+ fft and inverse_fft do not modify their arguments
+ fft and inverse_fft take 1 argument (complex), not 2
New items in core:
+ * new functions inverse_erf, inverse_erfc
New items in share:
+ * package hyperint: integration of some algebraic functions
+
+ * package hypergeometric: hypergeometric functions
+
+ * package linearalgebra: new function determinate_by_lu
+
+ * package abs_integrate: new functions floor_int, if_int
+
+ * package simplify_sum: extended Gosper algorithm
Other revisions:
+ * exp: rework implementation
+
+ * realpart, imagpart, cabs, carg: rework implementation
+
+ * revise exponential integral functions
+
+ * apropos: argument is a string, return Maxima user symbols only
+
+ * regularize implmentation of constant declaration
+
+ * pass options from Maxima command line to Lisp
+
+ * regularize use of some special variables
+
+ * package dynamics: revisions
+
+ * package fft: accept list as argument, other revisions
+
+ * package ezunits: revise code, revise and expand documentation
+
+ * package stats: test for the difference of two proportions
+
+ * package sarag: algorithm for the multivariate certificate
+
+ * package descriptive: more options for barsplot
+
+ * package draw: new object "mesh", new options
