GramSchmidt.Solve has different behavior (SparseMatrix vs DenseMatrix)


Using SparseMatrix I get coefficients equal to zero, but when I use DenseMatrix, I get nonzero values for all coefs. Program to reproduce attached. Run and check standard output for differences. For now I will just use DenseMatrix, since that result seems to make more sense.

This was using 2009.8 Beta, managed code.

I'll have a fix in early next week. Thanks, Marcus

The problem was how we the sparse vector and matrices were testing for zero values.
