Scale vector SSCAL/DSCAL/CSCAL/CSSCAL/CSCALC/ZSCAL/ZDSCAL/ZSCALC
Name SSCAL/DSCAL/CSCAL/CSSCAL/CSCALC/ZSCAL/ZDSCAL/ZSCALC
Scale vector
Purpose Given a real or complex scalar a and a real or complex vector x of length n,
these subprograms perform the vector scaling operations
where is the complex conjugate of x. The vector can be stored in a
one-dimensional array or in either a row or a column of a two-dimensional
array.
Usage VECLIB:
