这里，当我在任何矩阵中分配值时在同一个块中打印值

..正在给出正确的结果...但是如果我尝试

在另一个块中单独打印值...一些垃圾值

正在打印....说forr rgb1 [] [] ....它给出了正确的

值...（a）.. bt一些垃圾值在.........

（b）.......并且没有代码超出

for（i = 0 ; i< height; i ++）

{

for（j = 0; j< width; j ++）

{

t = rgb1 [i] [j];

// printf（"％d \ n"，t）;

//延迟（100） ;

for（i = 0; i< tmp; i ++）

{

if（sum_hist [i] [0] == t ）

index = sum_hist [i] [1];

}

index = index-min;

RGB1 [i] [j] = ABS（指数* 255 / p）;

// printf（"％d％d \ n"，t，rgb1 [i] [j]）;

//延迟（ 100）;

}

}

正在运行.......

plz澄清一次为从前面的讨论....我不知何故

清楚地看到我的问题的解决方案... PLZ整理出来

再一次......

感谢你..

Here, when I am assigning values in any matrix and printing the values
within the same block..it is giving the correct result...but if I try
to print the values separately in another block...some garbage values
are getting printed....say forr rgb1[][]....it is giving correct
values in ..(a)..bt some garbage values are there in .........
(b).......and no code beyond
for(i=0;i<height;i++)
{
for(j=0;j<width;j++)
{
t=rgb1[i][j];
//printf("%d\n",t);
//delay(100);
for(i=0;i<tmp;i++)

index=sum_hist[i][1];
}
index=index-min;
rgb1[i][j]=abs(index*255/p);
//printf("%d %d\n",t,rgb1[i][j]);
//delay(100);
}
}
is running.......
plz clarify once as from the previous discussion....I somehow not
getting a clear view of solutions of my problems...plz sort it out
once again...
thanking you..
