Create RGB from Matrices

[Gurdz50]

Hello All,

I am new to matlab and am wondering if there is a function available that is able to create an RGB image from a number of matrices which are of the format:

Matrix1: [0.06, 0.02; 0.3, 0.02]
Matrix2: [0.09, 0.01; 0.7, 0.03]
Matrix3: [0.1, 0.03; 0.4, 0.9]

Where each matrix represents a ratio of Red, Green or Blue. I would like to show the 3 matricies as one matrix (same dimensions as the above) with each cell having a double representation of the RGB value.

I hope my query is clear, many thanks for your help in advance.

MATLAB can use an MxNx3 matrix to represent a RGB image, with each MxN submatrix representing RGB color intensities. The help on the image command can explain this further.

If you have three MxN matricies red, green, blue you can create the RGB matrix in several ways. I have used the following two: (this assumes you have already defined m, n, red, green and blue)

I = zeros(m, n, 3);
I(:, :, 1) = red;
I(:, :, 2) = green;
I(:, :, 3) = blue;

Or alternately:

I = reshape([red; green; blue], m, n, 3);
