I have a 26x26 matrix 'A' of type double. I want to sum all of its elements using S = sum(A, 'all').
I keep getting the following error:
Error using sum
Invalid option. Option must be 'double', 'native', 'default', 'omitnan' or 'includenan'.
Can someone help me with this? My matrix is of the correct type, so I am not sure what's wrong.

I assume sum(X,'all') is implemented as sum(X(:)) at the intermediate interface level before the sum hoerachy and low-level CPU instruction occurs, so I think yes, they should return the same result.

sum(A(:)) % if it doesn't work either upload your matrix as .mat file

Image Analyst: clicking on the "Buy MATLAB and Simulink Student Suite" button on this page brings up the store page for the Student Version of release R2018b.
