code5_var

快速傅立叶变换程序代码,学信号的同学,可要注意了

# code 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 -.

dc->transpose		d	0 -transpose tra - whether to transpose A when writing it
dc->cheap		d	1 -cheap c		-	don't make inverse, go direct to alist repn (no choice in code5)
dc->N			d	10 -n N			-	horizontal size
>No UC
dc->NS			d	10 - -			-	size of signal block 
>CU
dc->N1			d	0 -n1 N1	- Number of columns with weight 1 (code6 only)
dc->M			d	0 -m M			-	other dimension
dc->seed		ld	125 -seed seed 		-	seed
#	whether to measure hamming distances between columns
dc->hd			d	3	-hd hd		-	this is used when generating the matrix
dc->t1			f	3 -t1 t1		-	number per col
dc->t2			f	0.0 -t2 t2		-	number per col (defaults to t1)
dc->verbose		d	1 -v verbosity		-	-
dc->outfile		s	- -o outfile	dc->out=2; 	Default MNC4/N.t1.t2.seed
dc->out			d	1 -out out		-	whether to print alist
dc->stair		d	0 -stair 2/1/0 - make a slope(2) or staircase (1) for the first chunk of matrix
dc->maxattempts		d	20 -maxa maxattempts - maximum number of attempts per column to avoid overlap with other cols
>PU  fprintf(fp,"\n");
