rmbnd_var

快速傅立叶变换程序代码,学信号的同学,可要注意了

# bnd variables
#
# file to be read by commander.p
# each line is turned into a structure entry   	(str)
#     	a default-setting entry			(def)
#     	a usage-printing entry			(usg)
# 	and a command line reading entry	(clr)
# of these, the S, U and C can be disabled by >No S, etc.
# and the D can be disabled by -.
#
# variable    		type deflt flag  short_name extra_action long_name
#
# BND is essentially parameter-free; you only have to decide when to
# give up. For numerical reasons a clipping rule was introduced but it
# only very rarely makes any difference.
# the fudge procedure is not needed but is investigated as a research 
# possiblity.

>No CU
bndc->loop	d 0 - - - - 
>CU
bndc->writelog	d 0 -bndlogn n - number of states to log
# added 97 02 : write_intermediate_states
