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 scalarsame type as x exp(xS, y)ri,j = yi,j ^ xS xS must be a scalar
y can be any typesame 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 xsame type as x and y
- Note: The operator prefix '?' combined with the power operator '^' can be used instead of this function.
