The ParametricDerivatives method finds the parametric derivatives of a LAVF object. The parametric derivatives are returned as a list of functions.
The method is front-end to the corresponding method of a LHPDE object. That is, let L be a LAVF object and S be its determining system as a LHPDE object (i.e. S = GetDeterminingSystem(L)), then the call ParametricDerivatives(L) is equivalent to ParametricDerivatives(S). All remaining input arguments will be passed down to its determining system S level. See the method ParametricDerivatives of a LHPDE object for more detail.
This method is associated with the LAVF object. For more detail, see Overview of the LAVF object.
First, construct an indeterminate vector field and a determining system, then construct an LAVF object from them...
Now we can find the parametric derivatives of L...
The ParametricDerivatives command was introduced in Maple 2020.
