Zswap() Sub Zswap ( N As  Long, ZX_I As  Complex, ZY_I As  Complex, Optional IncX As  Long = 1, Optional IncY As  Long = 1  ) y <-> x (complex vector) (BLAS 1) Purpose This routine interchanges two complex vectors. Parameters [in] N Number of elements in vectors x and y. (If N <= 0, returns without computation) [in,out] ZX_I An element X(I) of the array X(). [in] Starting from this location, vector x is stored with element spacing IncX. [out] Starting from this location, vector y is stored with element spacing IncX. [in,out] ZY_I An element Y(I) of the array Y(). [in] Starting from this location, vector y is stored with element spacing IncY. [out] Starting from this location, vector x is stored with element spacing IncY. [in] IncX (Optional) Element spacing of vector x in the array X(). (default = 1) [in] IncY (Optional) Element spacing of vector y in the array Y(). (default = 1) Reference BLAS
