Parameters

SIDE  String

(input) CHARACTER*1 = 'L': apply H or H' from the Left = 'R': apply H or H' from the Right

TRANS  String

(input) CHARACTER*1 = 'N': apply H (No transpose) = 'C': apply H' (Transpose)

DIRECT  String

(input) CHARACTER*1 Indicates how H is formed from a product of elementary reflectors = 'F': H = H(1) H(2) . . . H(k) (Forward, not supported yet) = 'B': H = H(k) . . . H(2) H(1) (Backward)

STOREV  String

(input) CHARACTER*1 Indicates how the vectors which define the elementary reflectors are stored: = 'C': Columnwise (not supported yet) = 'R': Rowwise

M  Int32

(input) INTEGER The number of rows of the matrix C.

N  Int32

(input) INTEGER The number of columns of the matrix C.

K  Int32

(input) INTEGER The order of the matrix T (= the number of elementary reflectors whose product defines the block reflector).

L  Int32

(input) INTEGER The number of columns of the matrix V containing the meaningful part of the Householder reflectors. If SIDE = 'L', M .GE. L .GE. 0, if SIDE = 'R', N .GE. L .GE. 0.

V  Double

(input) DOUBLE PRECISION array, dimension (LDV,NV). If STOREV = 'C', NV = K; if STOREV = 'R', NV = L.

offset_v  Int32

 

LDV  Int32

(input) INTEGER The leading dimension of the array V. If STOREV = 'C', LDV .GE. L; if STOREV = 'R', LDV .GE. K.

T  Double

(input) DOUBLE PRECISION array, dimension (LDT,K) The triangular K-by-K matrix T in the representation of the block reflector.

offset_t  Int32

 

LDT  Int32

(input) INTEGER The leading dimension of the array T. LDT .GE. K.

C  Double

(input/output) DOUBLE PRECISION array, dimension (LDC,N) On entry, the M-by-N matrix C. On exit, C is overwritten by H*C or H'*C or C*H or C*H'.

offset_c  Int32

 

LDC  Int32

(input) INTEGER The leading dimension of the array C. LDC .GE. max(1,M).

WORK  Double

(workspace) DOUBLE PRECISION array, dimension (LDWORK,K)

offset_work  Int32

 

LDWORK  Int32

(input) INTEGER The leading dimension of the array WORK. If SIDE = 'L', LDWORK .GE. max(1,N); if SIDE = 'R', LDWORK .GE. max(1,M).
