Run | ***PURPOSE Copy a vector. ***CATEGORY D1A5 ***TYPE DOUBLE PRECISION (SCOPY-S, DCOPY-D, CCOPY-C, ICOPY-I) ***KEYWORDS BLAS, COPY, LINEAR ALGEBRA, 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) DX double precision vector with N elements INCX storage spacing between elements of DX DY double precision vector with N elements INCY storage spacing between elements of DY --Output-- DY copy of vector DX (unchanged if N .LE. 0) Copy double precision DX to double precision DY. For I = 0 to N-1, copy DX(LX+I*INCX) to DY(LY+I*INCY), where LX = 1 if INCX .GE. 0, else LX = 1+(1-N)*INCX, and LY is defined in a similar way using INCY. ***REFERENCES C. L. Lawson, R. J. Hanson, D.
