sgesc2.f(3) LAPACK sgesc2.f(3)NAMEsgesc2.f-SYNOPSISFunctions/Subroutines subroutine sgesc2 (N, A, LDA, RHS, IPIV, JPIV, SCALE) SGESC2 solves a system of linear equations using the LU factorization with complete pivoting computed by sgetc2.Function/Subroutine Documentation subroutine sgesc2 (integerN, real, dimension( lda, * )A, integerLDA, real, dimension( * )RHS, integer, dimension( * )IPIV, integer, dimension( * )JPIV, realSCALE) SGESC2 solves a system of linear equations using the LU factorization with complete pivoting computed by sgetc2. Purpose: SGESC2 solves a system of linear equations A * X = scale* RHS with a general N-by-N matrix A using the LU factorization with complete pivoting computed by SGETC2. Parameters: N N is INTEGER The order of the matrix A. A A is REAL array, dimension (LDA,N) On entry, the LU part of the factorization of the n-by-n matrix A computed by SGETC2: A = P * L * U * Q LDA LDA is INTEGER The leading dimension of the array A. LDA >= max(1, N). RHS RHS is REAL array, dimension (N). On entry, the right hand side vector b. On exit, the solution vector X. IPIV IPIV is INTEGER array, dimension (N). The pivot indices; for 1 <= i <= N, row i of the matrix has been interchanged with row IPIV(i). JPIV JPIV is INTEGER array, dimension (N). The pivot indices; for 1 <= j <= N, column j of the matrix has been interchanged with column JPIV(j). SCALE SCALE is REAL On exit, SCALE contains the scale factor. SCALE is chosen 0 <= SCALE <= 1 to prevent owerflow in the solution. Author: Univ. of Tennessee Univ. of California Berkeley Univ. of Colorado Denver NAG Ltd.
