Bug: size(I, 1)*size(I, 2) returns size(I, 1) Instead of Product

I = imread('image.png');

Why does

size(I, 1)*size(I, 2)

return the value of size(I, 1) instead of the product? It gives the product if I do

a = size(I, 1);
b = size(I, 2);
a*b

This works for me. Let's make sure you haven't overloaded the size function. What does this command return?

which -all size

Also check if the variable I has size 1 in the second dimension.
