Element-wise operations	599c333915e0ea32d04d4bec	5		Operaciones de elementos sabios

Description

Implementar operaciones básicas de matriz de matriz de elementos y matriz escalar.

Implementar:

:: * Además

:: * resta

:: * multiplicación

:: * división

:: * exponenciación

El primer parámetro será la operación a realizar, por ejemplo: "m_add" para la adición de matriz y "s_add" para la adición escalar. Los parámetros segundo y tercero serán las matrices sobre las que se realizarán las operaciones.
