SYNOPSIS DOUBLE COMPLEX FUNCTION CDOTUI(NZ, X, INDX, Y) DOUBLE COMPLEX X(*), Y(*) INTEGER NZ INTEGER INDX(*) DOUBLE COMPLEX FUNCTION CDOTUI_64(NZ, X, INDX, Y) DOUBLE COMPLEX X(*), Y(*) INTEGER*8 NZ INTEGER*8 INDX(*) F95 INTERFACE DOUBLE COMPLEX FUNCTION DOTUI(NZ, X, INDX, Y) COMPLEX(8), DIMENSION(:) :: X, Y INTEGER :: NZ INTEGER, DIMENSION(:) :: INDX DOUBLE COMPLEX FUNCTION DOTUI_64(NZ, X, INDX, Y) COMPLEX(8), DIMENSION(:) :: X, Y INTEGER(8) :: NZ INTEGER(8), DIMENSION(:) :: INDX C INTERFACE #include <sunperf.h> doublecomplex zdotui (const int nz, const doublecomplex* x, const int* indx, const doublecomplex* y); doublecomplex zdotui_64 (const long nz, const doublecomplex* x, const long* indx, const doublecomplex* y); PURPOSE ZDOTUI Compute the complex unconjugated indexed dot product of a com- plex sparse vector x stored in compressed form with a complex vector y in full storage form. dot = 0 do i = 1, n dot = dot + x(i) * y(indx(i)) enddo ARGUMENTS NZ (input) Number of elements in the compressed form. Unchanged on exit. X (input) Vector in compressed form. Unchanged on exit. INDX (input) Vector containing the indices of the compressed form. It is assumed that the elements in INDX are distinct and greater than zero. Unchanged on exit. Y (input) Vector in full storage form. Only the elements corresponding to the indices in INDX will be accessed. 3rd Berkeley Distribution 7 Nov 2015 zdotui(3P)
