clascl.f(3) LAPACK clascl.f(3) NAME
clascl.f - SYNOPSIS
Functions/Subroutines subroutine clascl (TYPE, KL, KU, CFROM, CTO, M, N, A, LDA, INFO) CLASCL Function/Subroutine Documentation subroutine clascl (characterTYPE, integerKL, integerKU, realCFROM, realCTO, integerM, integerN, complex, dimension( lda, * )A, integerLDA, integerINFO) CLASCL Purpose: CLASCL multiplies the M by N complex matrix A by the real scalar CTO/CFROM. This is done without over/underflow as long as the final result CTO*A(I,J)/CFROM does not over/underflow. TYPE specifies that A may be full, upper triangular, lower triangular, upper Hessenberg, or banded. Parameters: TYPE TYPE is CHARACTER*1 TYPE indices the storage type of the input matrix. = 'G': A is a full matrix. = 'L': A is a lower triangular matrix. = 'U': A is an upper triangular matrix. = 'H': A is an upper Hessenberg matrix. = 'B': A is a symmetric band matrix with lower bandwidth KL and upper bandwidth KU and with the only the lower half stored. = 'Q': A is a symmetric band matrix with lower bandwidth KL and upper bandwidth KU and with the only the upper half stored. = 'Z': A is a band matrix with lower bandwidth KL and upper bandwidth KU. See CGBTRF for storage details. KL KL is INTEGER The lower bandwidth of A. Referenced only if TYPE = 'B', 'Q' or 'Z'. KU KU is INTEGER The upper bandwidth of A. Referenced only if TYPE = 'B', 'Q' or 'Z'. CFROM CFROM is REAL CTO CTO is REAL The matrix A is multiplied by CTO/CFROM. A(I,J) is computed without over/underflow if the final result CTO*A(I,J)/CFROM can be represented without over/underflow. CFROM must be nonzero. M M is INTEGER The number of rows of the matrix A. M >= 0. N N is INTEGER The number of columns of the matrix A. N >= 0. A A is COMPLEX array, dimension (LDA,N) The matrix to be multiplied by CTO/CFROM. See TYPE for the storage type. LDA LDA is INTEGER The leading dimension of the array A. LDA >= max(1,M). INFO INFO is INTEGER 0 - successful exit <0 - if INFO = -i, the i-th argument had an illegal value.
