LPFSGaussianLens

public LPFSGaussianLens(float mm,
                        float lp)

create a lens with a given maximum magnification factor

Parameters:

mm - maximum magnification factor, mm in [0,+inf[

lp - value of L(P), the Lp-metrics defining the lens' shape, in ]0,+inf[

LPFSGaussianLens

public LPFSGaussianLens(float mm,
                        float lp,
