How to create a colored grid of 3 matrices, representing the RGB-colors?

So I have 3 matrices, combined they represent a RGB-color in each cell. So the first matrix is the R-part, the second the G-part and the last one the B-part. I hope this is understandable.

Now I would like to create a colored grid where each cell is colored according to the RGB-color represented by the combination of the 3 matrices.

I tried using pcolor(). It works perfectly with only one matrix, but I don't know how or if it is even possible to use all 3 matrices for this.

Does anybody know how to do this?

------ An easy example: ----

Matrix1 = [1]

Matrix2 = [0]

Matrix3 = [0]

=> I want a grid with only one cell, colored in [1 0 0], so in red.

If you want an RGB image, why not just make an RGB image and display it using image() or imshow()?

R = rand(3);
G = rand(3);
B = rand(3);

RGB = cat(3,R,G,B);

image(RGB)

I don't know why you're creating everything in separate arrays to begin with. I find that it's rarely necessary to split an RGB image.
