I have an original image of dimension 300x300x3 (RGB)
after removing some entries, I apply an algorithm to reconstuct the original image.
Now i want to find the relative error between the 2 images.

….
% I call my function norm_fro to calcuate the error
Erec(i)= norm_fro( X_origin , X_r ecovered);
….

% here is my norm_fro function
function f = norm_fro( X , Xhat )

f = norm(X -Xhat,’fro’)^2/norm(X,’fro’)^2;

end

I get this error
Error using norm
Input must be 2-D.
