Invalid data types. Input arrays must be double or single. Sparse inputs are not supported. Option must be ''transpose'', ''ctranspose'' or ''none''. Incorrect dimensions for matrix division. Check that the number of columns in the first array matches the number of columns in the second array, unless second input is scalar. Arrays have incompatible sizes. For every dimension beyond the first two, the dimension sizes for both arrays must either be the same, or one of them must be 1.
