Funklet
A Funklet is a general parameterization for a meqparm. At this moment only the Polc and the PolcLog are available.
For reference: the polc coeff have the following meaning:
v(f,t) = c00 + c01t + c10f + c11f t + c02t2 + c20f2 + ....
You can set the solvability mask:
coeff_mask : array of bool with same size as coeff. Eg. [[F,F,T],[F,F,F]] will only solve for the C02 coefficient.
