Computes the numerical QR factorization of $A$.

• householder_row_indices must have length symbolic.householder().len_householder_row_indices()
• tau_blocksize must have length A.ncols().
• householder_nrows must have length A.ncols().
• householder_ncols must have length A.ncols().
• r_values must have length symbolic.r_adjoint().len_values.
• householder_values must have length symbolic.householder().length_householder_values().
• tau_values must have length symbolic.householder().len_tau_values().

Warning

• Note that the matrix takes as input A.transpose(), not A.
