CSYTRS_AA_2STAGE
Purpose:
CSYTRS_AA_2STAGE solves a system of linear equations A*X = B with a complex symmetric matrix A using the factorization A = U**T*T*U or A = L*T*L**T computed by CSYTRF_AA_2STAGE.
- Parameters
UPLO
UPLO is CHARACTER*1 Specifies whether the details of the factorization are stored as an upper or lower triangular matrix. = 'U': Upper triangular, form is A = U**T*T*U; = 'L': Lower triangular, form is A = L*T*L**T.
N
N is INTEGER The order of the matrix A. N >= 0.
NRHS
NRHS is INTEGER The number of right hand sides, i.e., the number of columns of the matrix B. NRHS >= 0.
A
A is COMPLEX array, dimension (LDA,N) Details of factors computed by CSYTRF_AA_2STAGE.
LDA
LDA is INTEGER The leading dimension of the array A. LDA >= max(1,N).
TB
TB is COMPLEX array, dimension (LTB) Details of factors computed by CSYTRF_AA_2STAGE.
LTB
LTB is INTEGER The size of the array TB. LTB >= 4*N.
IPIV
IPIV is INTEGER array, dimension (N) Details of the interchanges as computed by CSYTRF_AA_2STAGE.
IPIV2
IPIV2 is INTEGER array, dimension (N) Details of the interchanges as computed by CSYTRF_AA_2STAGE.
B
B is COMPLEX array, dimension (LDB,NRHS) On entry, the right hand side matrix B. On exit, the solution matrix X.
LDB
LDB is INTEGER The leading dimension of the array B. LDB >= max(1,N).
INFO
INFO is INTEGER = 0: successful exit < 0: if INFO = -i, the i-th argument had an illegal value
