 ```ZUNGR2(l) ) ZUNGR2(l) NAME ZUNGR2 - generate an m by n complex matrix Q with orthonormal rows, SYNOPSIS SUBROUTINE ZUNGR2( M, N, K, A, LDA, TAU, WORK, INFO ) INTEGER INFO, K, LDA, M, N COMPLEX*16 A( LDA, * ), TAU( * ), WORK( * ) PURPOSE ZUNGR2 generates an m by n complex matrix Q with orthonormal rows, which is defined as the last m rows of a product of k elementary reflectors of order n Q = H(1)' H(2)' . . . H(k)' as returned by ZGERQF. ARGUMENTS M (input) INTEGER The number of rows of the matrix Q. M >= 0. N (input) INTEGER The number of columns of the matrix Q. N >= M. K (input) INTEGER The number of elementary reflectors whose product defines the matrix Q. M >= K >= 0. A (input/output) COMPLEX*16 array, dimension (LDA,N) On entry, the (m-k+i)-th row must contain the vector which defines the elementary reflector H(i), for i = 1,2,...,k, as returned by ZGERQF in the last k rows of its array argument A. On exit, the m-by-n matrix Q. LDA (input) INTEGER The first dimension of the array A. LDA >= max(1,M). TAU (input) COMPLEX*16 array, dimension (K) TAU(i) must contain the scalar factor of the elementary reflector H(i), as returned by ZGERQF. WORK (workspace) COMPLEX*16 array, dimension (M) INFO (output) INTEGER = 0: successful exit < 0: if INFO = -i, the i-th argument has an illegal value LAPACK version 3.0 15 June 2000 ZUNGR2(l)```
