| Description | simple versions: Yi = exp( Xi )
expanded versions: Yi = C * exp( A*Xi+B )
Euler's constant e is raised to the Xi'th power.
For cartesian complex numbers, the result can be stored either in cartesian complex format (VCF_exp), or in polar coordinates (VCF_exptoP).
Variants of the exponential function, like its complement (VF_expc), the hyperbolic functions (e.g. VF_sinh), or the Gaussian distribution (VF_Gauss) are also available; see chapter 4.6.7 about "Exponentials" before using VF_exp for sums or other combinations of exponentials - maybe the desired function already exists. |
