postinterp
The property Phase is described in posteval.
The property U specifies the solution for which the evaluation is carried out. If U is
not specified, then it is taken from fem.sol if it exists; otherwise it is the zero
vector.
The expressions ei are interpolated for one or several solutions. The properties
Solnum and T control what solutions are used for the evaluations. If Solnum is
provided, the solution indicated by the indices provided with the Solnum property
are used. It T is provided, solutions are interpolated at the given times. The property
T can only be used for time dependent solutions. If neither Solnum nor T is
provided, a single solution is evaluated. For parametric and time-dependent
solutions, the final solution is used. For eigenvalue solution the first solution is used.
For time-dependent problems, the variable t can be used in the expressions ei. The
value of t is the interpolation time when the property T is provided, and the time
for the solution, when Solnum is used. Similarly, lambda and the parameter are
available as eigenvalues for eigenvalue problems and parameter value for parametric
problems, respectively.
A subsequent evaluation with [v1,v2,...,vn] =
postinterp(fem,e1,e2,...,en,pio,...) is faster than using xx instead of pio.
In this form of the call, only the properties Const, Phase, Solnum, T, and U are used.
Compatibility The properties Context, Cont, and Contorder are obsolete from FEMLAB 3.0.
In FEMLAB 3.0, the interpolation structure is as a Java object.
The property Variables has been renamed to Const in FEMLAB 2.3.
The syntax and capabilities of this function has changed since FEMLAB 2.1.
