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 description exp(x)ri,j = e ^ xi,j x can be any type
r has same type as xexp(x, yS)ri,j = yS ^ xi,j x can be any type, yS must be a scalar
r has same type as xexp(xS, y)ri,j = yi,j ^ xS xS must be a scalar, y can be any type
r has same type as yexp(x, y)ri,j = yi,j ^ xi,j x must be a vector or matrix
y must have the same type as xvectors
r has same type as x
exp(xS, y)
result[i] = y[i] ^ xS
exp(x, y)
result[i] = y[i] ^ x[i]
