Assigning RGB values to a new 3D RGB image

I am trying to apply a set of calculated RGB values as new values for a position in a m x n x 3 image. My attempt is shown in the code provided.

My error is in the line staticImage{i,j,:] = staticImage(1,j,newPixels) where i am trying to replace the layer at point i,j with the new RGB values 'newPixels'

Does anyone know how to do this?

staticImage(i,j,:) = [R,G,B];
