Exponential function

Usage: This function has several usage formats where the evaluation and the type of the result depends on. The table below shows the possible usages.

usage	evaluation	description
`exp(x)`	r_i,j = e ^ x_i,j	x can be any type r has same type as x
`exp(x, y_S)`	r_i,j = y_S ^ x_i,j	x can be any type, y_S must be a scalar r has same type as x
`exp(x_S, y)`	r_i,j = y_i,j ^ x_S	x_S must be a scalar, y can be any type r has same type as y
`exp(x, y)`	r_i,j = y_i,j ^ x_i,j	x must be a vector or matrix y must have the same type as xvectors r has same type as y

exp(xS, y)

result[i] = y[i] ^ xS

exp(x, y)

result[i] = y[i] ^ x[i]
