:fortran_help: " SUBROUTINE ZLASCL( TYPE, KL, KU, CFROM, CTO, M, N, A, LDA, INFO )\n\n\
* Purpose\n\
* =======\n\
*\n\
* ZLASCL multiplies the M by N complex matrix A by the real scalar\n\
* CTO/CFROM. This is done without over/underflow as long as the final\n\
* result CTO*A(I,J)/CFROM does not over/underflow. TYPE specifies that\n\
* A may be full, upper triangular, lower triangular, upper Hessenberg,\n\
* or banded.\n\
*\n\n\
* Arguments\n\
* =========\n\
*\n\
* TYPE (input) CHARACTER*1\n\
* TYPE indices the storage type of the input matrix.\n\
* = 'G': A is a full matrix.\n\
* = 'L': A is a lower triangular matrix.\n\
* = 'U': A is an upper triangular matrix.\n\
* = 'H': A is an upper Hessenberg matrix.\n\
* = 'B': A is a symmetric band matrix with lower bandwidth KL\n\
* and upper bandwidth KU and with the only the lower\n\
* half stored.\n\
* = 'Q': A is a symmetric band matrix with lower bandwidth KL\n\
* and upper bandwidth KU and with the only the upper\n\
* half stored.\n\
* = 'Z': A is a band matrix with lower bandwidth KL and upper\n\
* bandwidth KU. See ZGBTRF for storage details.\n\
*\n\
* KL (input) INTEGER\n\
* The lower bandwidth of A. Referenced only if TYPE = 'B',\n\
* 'Q' or 'Z'.\n\
*\n\
* KU (input) INTEGER\n\
* The upper bandwidth of A. Referenced only if TYPE = 'B',\n\
* 'Q' or 'Z'.\n\
*\n\
* CFROM (input) DOUBLE PRECISION\n\
* CTO (input) DOUBLE PRECISION\n\
* The matrix A is multiplied by CTO/CFROM. A(I,J) is computed\n\
* without over/underflow if the final result CTO*A(I,J)/CFROM\n\
* can be represented without over/underflow. CFROM must be\n\
* nonzero.\n\
*\n\
* M (input) INTEGER\n\
* The number of rows of the matrix A. M >= 0.\n\
*\n\
* N (input) INTEGER\n\
* The number of columns of the matrix A. N >= 0.\n\
*\n\
* A (input/output) COMPLEX*16 array, dimension (LDA,N)\n\
* The matrix to be multiplied by CTO/CFROM. See TYPE for the\n\
* storage type.\n\
*\n\
* LDA (input) INTEGER\n\
* The leading dimension of the array A. LDA >= max(1,M).\n\
*\n\
* INFO (output) INTEGER\n\
* 0 - successful exit\n\
* <0 - if INFO = -i, the i-th argument had an illegal value.\n\
