Detailed Description

Mathematical transformations of parameters.

Evaluate a simpel mathematical function (no if's or loops).

[fun_eval]
`var <var_name> ...`
Define all variables.
`const <expr> ...`
Evaluate constant expression (independant from the input data)
`eval <expr> ...`
Expressions to calculate the output frame from the input frame. The final result has to be stored in the variable 'ovec'.
`example ivec=<expr> ...`
Example of an input frame, used to calclutate the output vector length. By default a vector containing all ones is used.
