So for compatibility, Octave could support scalar_double \ scalar_int, scalar_float \ scalar_int, scalar_double \ int_matrix, scalar_float \ int_matrix if someone finds the time.

For reference, in Matlab 2016b

Left division incorrectly returns a scalar type, rather than a matrix type, for scalar_double \ integer_matrix.

Example code:

Since left-division isn't implemented for integer data types (see bug #51650) this case should also just throw an error about an unimplemented operator rather than calculating a value which is misleading.
