Parameters

[in]	side	PlasmaLeft : apply Q or Q^H from the Left; PlasmaRight : apply Q or Q^H from the Right.
[in]	trans	PlasmaNoTrans : Apply Q; Plasma_ConjTrans : Apply Q^H.
[in]	direct	Indicates how H is formed from a product of elementary reflectors PlasmaForward : H = H(1) H(2) . . . H(k) (Forward) PlasmaBackward : H = H(k) . . . H(2) H(1) (Backward)
[in]	storev	Indicates how the vectors which define the elementary reflectors are stored: PlasmaColumnwise PlasmaRowwise
[in]	m1	The number of columns of the tile A1. m1 >= 0.
[in]	n1	The number of rows of the tile A1. n1 >= 0.
[in]	m2	The number of columns of the tile A2. m2 >= 0.
[in]	n2	The number of rows of the tile A2. n2 >= 0.
[in]	k	The order of the matrix T (= the number of elementary reflectors whose product defines the block reflector).
[in]	l	The size of the triangular part of V
[in,out]	A1	On entry, the m1-by-n1 tile A1. On exit, A1 is overwritten by the application of Q.
[in]	lda1	The leading dimension of the array A1. lda1 >= max(1,n1).
[in,out]	A2	On entry, the m2-by-n2 tile A2. On exit, A2 is overwritten by the application of Q.
[in]	lda2	The leading dimension of the tile A2. lda2 >= max(1,n2).
[in]	V	(ldv,k) if storev = 'C' (ldv,m2) if storev = 'R' and side = 'L' (ldv,n2) if storev = 'R' and side = 'R' Matrix V.
[in]	ldv	The leading dimension of the array V. If storev = 'C' and side = 'L', ldv >= max(1,m2); if storev = 'C' and side = 'R', ldv >= max(1,n2); if storev = 'R', ldv >= k.
[out]	T	The triangular k-by-k matrix T in the representation of the block reflector. T is upper triangular by block (economic storage); The rest of the array is not referenced.
[in]	ldt	The leading dimension of the array T. ldt >= k.
[in,out]	work
[in]	ldwork	The leading dimension of the array work.
