An element of the output array is set to logical 1 true if either a or b contain a nonzero element at that same array location. Inputs a and b must either be the same size or have sizes that are compatible for example, a is an mbyn matrix and b is a scalar or 1byn row vector. A and b must have the same dimensions or one can be a scalar.
