我想实现3*50*50的数组的高斯滤波（5*5），代码前面都没有任何问题，添加以下代码后，程序调试不报错但是也没有输出，这是为什么啊？求大神指导。
for (k = 0; k < 3; k++)
{
for (i = 0; i < 50; i++)
{
if (i >= 0 && i <= 45)
{
for (j = 0; j < 50; j++)
{
if (j >= 0 && j <= 45)
{
pdftdl[k][i][j] = pdftdl[k][i][j] * smfilt[0][0] + pdftdl[k][i][j + 1] * smfilt[0][1] + pdftdl[k][i][j + 2] * smfilt[0][2] + pdftdl[k][i][j + 3] * smfilt[0][3] + pdftdl[k][i][j + 4] * smfilt[0][4]

看明白你这段代码 得1天
没有输出很有可能是没运行完，我看你在最后面打印了信息，或者 setjmp 加个异常捕获
“看明白你这段代码 得1天”这话没毛病。
建议替换代码，可以看看这个大佬的:
