Calculate a paired basis of logical operators of a CSScode. That is, given two bases of the homology H_1 and cohomology H^1 respectively, find and return a basis of H^1 which is ‘paired’ with that of H_1 by the nondegenerate bilinear form, i.e. the dot product.

Parameters:

  • basis1 – The basis of H_1.

  • basis2 – The basis of H^1.

Returns:

A basis of H^1 which is paired with basis1.
