Plotting a grid with cells colored different depending on their value

I have a 10x10 matrix, each element contains an integer value.

I'm looking for a way to visually represent this matrix. I want to have a grid (10x10) and each cell in the grid should be colored. Basically, each element should be the same number, and if the element is this number, I want a it to be green (for example); if it does not equal this value, I want it colored red.

I'm guessing this is possible, I just have no idea where to start with it!

Thanks.

You could use image() or scatter()

I agree with Walter. You can use image() or imshow(), combined with colormap() and colorbar.

But just as an interesting alternative, you might take a look at Steve Eddins's im2html() : http://blogs.mathworks.com/steve/2012/06/02/making-an-html-table-of-pixel-values-with-colored-cells/
