areEqual(PolySpace,PolySpace) -- approximate equality of subspaces spanned by polynomials

Synopsis

Description

Two spaces are approximately equal if the numericalImage of their union of their generators has the same dimension as both of them.

i1 : R = CC[x,y];
i2 : b = areEqual(polySpace matrix{{y^2,x^2+x*y}}, polySpace matrix{{x^2+x*y+y^2,y^2+0.00000001}})

o2 = true
