zlat2c.f(3) LAPACK zlat2c.f(3) NAME
zlat2c.f - SYNOPSIS
Functions/Subroutines subroutine zlat2c (UPLO, N, A, LDA, SA, LDSA, INFO) ZLAT2C Function/Subroutine Documentation subroutine zlat2c (characterUPLO, integerN, complex*16, dimension( lda, * )A, integerLDA, complex, dimension( ldsa, * )SA, integerLDSA, integerINFO) ZLAT2C Purpose: ZLAT2C converts a COMPLEX*16 triangular matrix, SA, to a COMPLEX triangular matrix, A. RMAX is the overflow for the SINGLE PRECISION arithmetic ZLAT2C checks that all the entries of A are between -RMAX and RMAX. If not the convertion is aborted and a flag is raised. This is an auxiliary routine so there is no argument checking. Parameters: UPLO UPLO is CHARACTER*1 = 'U': A is upper triangular; = 'L': A is lower triangular. N N is INTEGER The number of rows and columns of the matrix A. N >= 0. A A is COMPLEX*16 array, dimension (LDA,N) On entry, the N-by-N triangular coefficient matrix A. LDA LDA is INTEGER The leading dimension of the array A. LDA >= max(1,N). SA SA is COMPLEX array, dimension (LDSA,N) Only the UPLO part of SA is referenced. On exit, if INFO=0, the N-by-N coefficient matrix SA; if INFO>0, the content of the UPLO part of SA is unspecified. LDSA LDSA is INTEGER The leading dimension of the array SA. LDSA >= max(1,M). INFO INFO is INTEGER = 0: successful exit. = 1: an entry of the matrix A is greater than the SINGLE PRECISION overflow threshold, in this case, the content of the UPLO part of SA in exit is unspecified.

dlat2s.f - SYNOPSIS
Functions/Subroutines subroutine dlat2s (UPLO, N, A, LDA, SA, LDSA, INFO) DLAT2S converts a double-precision triangular matrix to a single-precision triangular matrix. Function/Subroutine Documentation subroutine dlat2s (characterUPLO, integerN, double precision, dimension( lda, * )A, integerLDA, real, dimension( ldsa, * )SA, integerLDSA, integerINFO) DLAT2S converts a double-precision triangular matrix to a single-precision triangular matrix. Purpose: DLAT2S converts a DOUBLE PRECISION triangular matrix, SA, to a SINGLE PRECISION triangular matrix, A. RMAX is the overflow for the SINGLE PRECISION arithmetic DLAS2S checks that all the entries of A are between -RMAX and RMAX. If not the convertion is aborted and a flag is raised. This is an auxiliary routine so there is no argument checking. Parameters: UPLO UPLO is CHARACTER*1 = 'U': A is upper triangular; = 'L': A is lower triangular. N N is INTEGER The number of rows and columns of the matrix A. N >= 0. A A is DOUBLE PRECISION array, dimension (LDA,N) On entry, the N-by-N triangular coefficient matrix A. LDA LDA is INTEGER The leading dimension of the array A. LDA >= max(1,N). SA SA is REAL array, dimension (LDSA,N) Only the UPLO part of SA is referenced. On exit, if INFO=0, the N-by-N coefficient matrix SA; if INFO>0, the content of the UPLO part of SA is unspecified. LDSA LDSA is INTEGER The leading dimension of the array SA. LDSA >= max(1,M). INFO INFO is INTEGER = 0: successful exit. = 1: an entry of the matrix A is greater than the SINGLE PRECISION overflow threshold, in this case, the content of the UPLO part of SA in exit is unspecified.
