Parameters

TRANS  String

(input) CHARACTER*1 Specifies the form of the system of equations: = 'N': A * X = B (No transpose) = 'T': A'* X = B (Transpose) = 'C': A'* X = B (Conjugate transpose = Transpose)

N  Int32

(input) INTEGER The order of the matrix A. N .GE. 0.

NRHS  Int32

(input) INTEGER The number of right hand sides, i.e., the number of columns of the matrix B. NRHS .GE. 0.

A  Double

(input) DOUBLE PRECISION array, dimension (LDA,N) The factors L and U from the factorization A = P*L*U as computed by DGETRF.

offset_a  Int32

 

LDA  Int32

(input) INTEGER The leading dimension of the array A. LDA .GE. max(1,N).

IPIV  Int32

(input) INTEGER array, dimension (N) The pivot indices from DGETRF; for 1.LE.i.LE.N, row i of the matrix was interchanged with row IPIV(i).

offset_ipiv  Int32

 

B  Double

(input/output) DOUBLE PRECISION array, dimension (LDB,NRHS) On entry, the right hand side matrix B. On exit, the solution matrix X.

offset_b  Int32

 

LDB  Int32

(input) INTEGER The leading dimension of the array B. LDB .GE. max(1,N).

INFO  Int32

(output) INTEGER = 0: successful exit .LT. 0: if INFO = -i, the i-th argument had an illegal value
