* Returns the Nesterov-Todd scaling W at points s and z, and stores the scaled variable in lmbda. W * z = W^{-T} * s = lmbda. W is a MatrixSet with entries: - W['dnl']: positive vector - W['dnli']: componentwise inverse of W['dnl'] - W['d']: positive vector - W['di']:
(s, z, lmbda *matrix.FloatMatrix, dims *sets.DimensionSet, mnl int)
