DSCAL Class

***PURPOSE Multiply a vector by a constant. ***CATEGORY D1A6 ***TYPE DOUBLE PRECISION (SSCAL-S, DSCAL-D, CSCAL-C) ***KEYWORDS BLAS, LINEAR ALGEBRA, SCALE, VECTOR ***AUTHOR Lawson, C. L., (JPL) Hanson, R. J., (SNLA) Kincaid, D. R., (U. of Texas) Krogh, F. T., (JPL) ***DESCRIPTION B L A S Subprogram Description of Parameters --Input-- N number of elements in input vector(s) DA double precision scale factor DX double precision vector with N elements INCX storage spacing between elements of DX --Output-- DX double precision result (unchanged if N.LE.0) Replace double precision DX by double precision DA*DX. For I = 0 to N-1, replace DX(IX+I*INCX) with DA * DX(IX+I*INCX), where IX = 1 if INCX .GE. 0, else IX = 1+(1-N)*INCX. ***REFERENCES C. L. Lawson, R. J. Hanson, D. R. Kincaid and F. T.
