Implement basic element-wise matrix-matrix and scalar-matrix operations.
Implement:
::* addition
::* subtraction
::* multiplication
::* division
::* exponentiation
The first parameter will be the operation to be performed, for example : "m_add" for matrix addition and "s_add" for scalar addition. The second and third parameters will be the matrices on which the operations are to be performed.
operation
is a function.
