Hi, all
I have a matrix 49x49,
It's contains 0~10000 value.
When I plot this matrix, use colorbar.
But the zero value point,I want to use white color to present this point.
How can I do?
Thanks.

When you post the relevant part of your code, inserting modifications is much easier. Test data can usually created by RAND.

Get the colormap, set 0 to white, then reapply it.
cm = colormap;
cm(0, :) = [255 255 255];
colormap(cm);

That's right. The values must be in the range 0-1, not 0-255 even though it's really 255. So try this:
cm(1, :) = [1 1 1];
