What about color intensity

I want to display an image with red, green and blue intensity, between 1:5 lines and 2:8 columns, Thanks.

Do you want a red stripe, a green stripe, and a blue stripe in lines (rows) 1-5? If you had one color per row, then that's 3 rows, so what color do you want rows 4 and 5 to be? Same for the vertical stripes going down the image in the 7 columns 2 through 8? You have 3 colors and 7 columns. 7 is not a multiple of 3. So, what color goes into what column?

MyImage = zeros(3, 8, 3);

MyImage(1,:,1) = 1;  %red
MyImage(1,:,2) = 0;
MyImage(1,:,3) = 0;

MyImage(2,:,1) = 0;  %green
MyImage(2,:,2) = 1;
MyImage(2,:,3) = 0;

MyImage(3,:,1) = 0;  %blue
MyImage(3,:,2) = 0;
MyImage(3,:,3) = 1;

image(MyImage)
