HPL_dlaswp04N(3) HPL Library Functions HPL_dlaswp04N(3) NAME HPL_dlaswp04N - copy rows of U in A and replace them with columns of W. SYNOPSIS #include "hpl.h" void HPL_dlaswp04N( const int M0, const int M1, const int N, double * U, const int LDU, double * A, const int LDA, const double * W0, const double * W, const int LDW, const int * LINDXA, const int * LINDXAU ); DESCRIPTION HPL_dlaswp04N copies M0 rows of U into A and replaces those rows of U with columns of W. In addition M1 - M0 columns of W are copied into rows of U. ARGUMENTS M0 (local input) const int On entry, M0 specifies the number of rows of U that should be copied into A and replaced by columns of W. M0 must be at least zero. M1 (local input) const int On entry, M1 specifies the number of columns of W that should be copied into rows of U. M1 must be at least zero. N (local input) const int On entry, N specifies the length of the rows of U that should be copied into A. N must be at least zero. U (local input/output) double * On entry, U points to an array of dimension (LDU,N). This array contains the rows that are to be copied into A. LDU (local input) const int On entry, LDU specifies the leading dimension of the array U. LDU must be at least MAX(1,M1). A (local output) double * On entry, A points to an array of dimension (LDA,N). On exit, the rows of this array specified by LINDXA are replaced by rows of U indicated by LINDXAU. LDA (local input) const int On entry, LDA specifies the leading dimension of the array A. LDA must be at least MAX(1,M0). W0 (local input) const double * On entry, W0 is an array of size (M-1)*LDW+1, that contains the destination offset in U where the columns of W should be copied. W (local input) const double * On entry, W is an array of size (LDW,M0+M1), that contains data to be copied into U. For i in [M0..M0+M1), the entries W(:,i) are copied into the row W0(i*LDW) of U. LDW (local input) const int On entry, LDW specifies the leading dimension of the array W. LDW must be at least MAX(1,N+1). LINDXA (local input) const int * On entry, LINDXA is an array of dimension M0 containing the local row indexes A into which rows of U are copied. LINDXAU (local input) const int * On entry, LINDXAU is an array of dimension M0 that contains the local row indexes of U that should be copied into A and replaced by the columns of W.
