f77_orgr2 Interface
public interface f77_orgr2
Generic old style interface for ORGR2. Supports s, d. See also: mfi_orgr2, sorgr2, dorgr2.
Subroutines
public pure subroutine sorgr2(m, n, k, a, lda, tau, work, info)
Original interface for SORGR2 See also: mfi_orgr2, f77_orgr2. This routine generates an real(REAL32) matrix with orthonormal rows, which is defined as the last rows of a product of elementary reflectors of order . as returned by sgerqf.
