Convert the matrix to the color and making images

Please, can anyone tell me how, if I have values in table and I see it like a matrix, and I want to create an image so that some elements of the matrix are show as a certain color? Means that the whole matrix is converted into an image. Is this possible to do it in Matlab or can anyone suggested another program?

Your matrix is already an image. Just use imshow() (my favorite), image(), or imagesc() to display it. You can also use colormap() and colorbar() if it's a grayscale or indexed image. DO NOT use pcolor().
