srscl.f(3) LAPACK srscl.f(3) NAME
srscl.f - SYNOPSIS
Functions/Subroutines subroutine srscl (N, SA, SX, INCX) SRSCL Function/Subroutine Documentation subroutine srscl (integerN, realSA, real, dimension( * )SX, integerINCX) SRSCL Purpose: SRSCL multiplies an n-element real vector x by the real scalar 1/a. This is done without overflow or underflow as long as the final result x/a does not overflow or underflow. Parameters: N N is INTEGER The number of components of the vector x. SA SA is REAL The scalar a which is used to divide each component of x. SA must be >= 0, or the subroutine will divide by zero. SX SX is REAL array, dimension (1+(N-1)*abs(INCX)) The n-element vector x. INCX INCX is INTEGER The increment between successive values of the vector SX. > 0: SX(1) = X(1) and SX(1+(i-1)*INCX) = x(i), 1< i<= n Author: Univ. of Tennessee Univ. of California Berkeley Univ. of Colorado Denver NAG Ltd.

zdrscl.f - SYNOPSIS
Functions/Subroutines subroutine zdrscl (N, SA, SX, INCX) ZDRSCL multiplies a vector by the reciprocal of a real scalar. Function/Subroutine Documentation subroutine zdrscl (integerN, double precisionSA, complex*16, dimension( * )SX, integerINCX) ZDRSCL multiplies a vector by the reciprocal of a real scalar. Purpose: ZDRSCL multiplies an n-element complex vector x by the real scalar 1/a. This is done without overflow or underflow as long as the final result x/a does not overflow or underflow. Parameters: N N is INTEGER The number of components of the vector x. SA SA is DOUBLE PRECISION The scalar a which is used to divide each component of x. SA must be >= 0, or the subroutine will divide by zero. SX SX is COMPLEX*16 array, dimension (1+(N-1)*abs(INCX)) The n-element vector x. INCX INCX is INTEGER The increment between successive values of the vector SX. > 0: SX(1) = X(1) and SX(1+(i-1)*INCX) = x(i), 1< i<= n Author: Univ. of Tennessee Univ. of California Berkeley Univ. of Colorado Denver NAG Ltd.
