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



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
