How can I add arrays in an image

Question

I have image with size of 106X351 logical.When I want to sum all of arrays in this image, I've faced with this error "Index exceeds matrix dimensions."

s=sum(im);

Is there any function that I can use?

Answer 1

If your error is in that line, most likely you have a variable named sum. Try clearing the workspace and change the name of any variables named sum in you script and give it a try
