  Gradient(function, [varlist], [mode])
function
This is defined by the mode parameter as cartesian coordinates (mode=0), cylindrical coordinates (mode=1) or spherical coordinates (mode=2).

[varlist]
This parameter is optional and when not defined uses the following values.
mode=0 : [x, y, z]
mode=1 : [r, Φ, z]
mode=2 : [r, θ, Φ]

When other variables are used these have to be declared in the varlist as [ var1 , var2 , var3 , ...].

[mode]
The default value is 0.


Description
Returns the Gradient of the function.

This is normally denoted as Grad(F) = ∇F


Examples
