#include"STDIO.H"
#include"MATH.H"
#define M 8
#define N 8
#define P 3.141593
void Print(float a[M][N])
{ int i,j;
for(i=0;i<M;i++)
{for(j=0;j<N;j++)
Printf("%f,",a[i][j]);
Printf("\n");
}}
void Fast(float a[N][M], float b[M][N])
{int i,j;
for(i=0;i<M;i++)
for(j=0;j<N;j++)
a[j][i]=b[i][j];
}
void Mult(float a[M][N],float b[M][N] , float c[M][N])
{int i,j,k;
float sum;
for(i=0;i<M;i++)
for(j=0;j<N;j++)
{sum=0;
for(k=0;k<N;k++)
sum=sum+a[i][k]*b[k][j];
c[i][j]=sum;
}}
main()
{float DCT[M][N],TDCT[N][M];
float temp[M][N],F[M][N];
float Ck;
int i,j;
float f[M][N]={79,75,79,82,82,86,94,94,76,78,76,82,83,86,85,94,72,75,67,78,80,78,74,82,74,76,75,75,86,80,81,79,73,70,75,67,78,78,79,85,69,63,68,69,75,78,82,80,76,76,71,71,67,79,80,83,72,77,78,69,75,75,78,78};

结果是：
619.625000,-29.970915,8.623259,1.909263,1.625109,-3.936337,0.893177,1.515589,

改对的程序是：
#include <stdio.h>
#include <math.h>
#define M 8
#define N 8
#define P 3.141593
void Print(float a[M][N])
{ int i,j;
for(i=0;i<M;i++)
{for(j=0;j<N;j++)
printf("%f,",a[i][j]);
printf("\n");
}}
