I am writing a function that can take any number of 1D arrays representing coloured images. the output should be a 3D array to represent an image that represents the combined image? how would i write a matlab code that adds corresponding elements together from each of the input images?
For example, if we have 3 images as inputs, pixel 1 from image 1 + pixel 1 from image 2 + pixel 1 from image 3 = pixel 1 in the output image
Thanks :)

See my attached demo to average RGB images. Adapt as needed.

But you don't need to loop over rows and columns. You can just sum the entire image directly as I did in my answer:
sumImage = sumImage + double(thisImage); % Be sure to cast to double to prevent clipping.
