dftd.c

用C语言实现的离散傅里叶变换（DFT）的经典算法！比较实用！

#include "dsp1.h"
#include "dft.h"



main()
{
    extern long npt;
	extern int  inv;

	printf("select typek of transform\n");
	printf("\n");
	printf("0     for forward DFT\n");
	printf("1     for inverse DFT\n");

	scanf("%d",&inv);
	read_data();
	dft();
	save_data();
	exit(0);

	
}
