MultiprojectiveVarieties :: clean(MultirationalMap)

clean(MultirationalMap) -- clean the internal information of a multi-rational map

Synopsis

Description

This is only useful for comparing computation times for various algorithms.

i1 : Phi = 1_(PP_QQ^2);

o1 : MultirationalMap (automorphism of PP^2)
i2 : Psi = clean Phi;

o2 : MultirationalMap (rational map from PP^2 to PP^2)
i3 : Phi == Psi

o3 = true
i4 : Phi === Psi

o4 = false
