Class Drscl

  extended by org.netlib.lapack.Drscl

public class Drscl
extends java.lang.Object

Following is the description from the original
Fortran source.  For each array argument, the Java
version will include an integer offset parameter, so
the arguments may not match the description exactly.
Contact with any questions.

* .. * * Purpose * ======= * * DRSCL 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. * * Arguments * ========= * * N (input) INTEGER * The number of components of the vector x. * * SA (input) 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 (input/output) DOUBLE PRECISION array, dimension * (1+(N-1)*abs(INCX)) * The n-element vector x. * * INCX (input) 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 * * ===================================================================== * * ..
