Exponential function

Usage

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

usage	evaluation	data type of arguments	data type of result r
exp(x)	ri,j = e ^ xi,j	x can be any type	same type as x
exp(x, yS)	ri,j = yS ^ xi,j	x can be any type yS must be a scalar	same type as x
exp(xS, y)	ri,j = yi,j ^ xS	xS must be a scalar y can be any type	same type as y
exp(x, y)	ri,j = yi,j ^ xi,j	x must be a vector or matrix y must have the same type as x	same type as x and y

Note

Since its implementation, the element-wise operator '?' can be used instead of this function.
