Description
| ||||||

Generate an M-by-N real matrix Q with orthonormal columns.
- a (IN/OUT - matrix(M,N) On entry, the i-th column must contain the vector which defines the elementary reflector H(i), for i = 1,2,...,k, as returned by GEQRF in the first k columns of its array argument A. On exit, the M-by-N matrix Q.
- tau (IN - vector(K)) tau[i] must contain the scalar factor of the elementary reflector H(i), as returned by GEQRF.
