Oracle Solaris Studio Performance Library csrot(3P) NAME csrot - Apply a plane rotation SYNOPSIS SUBROUTINE CSROT(N, X, INCX, Y, INCY, C, S) REAL C, S COMPLEX X(*), Y(*) INTEGER N, INCX, INCY SUBROUTINE CSROT_64(N, X, INCX, Y, INCY, C, S) REAL C, S COMPLEX X(*), Y(*) INTEGER*8 N, INCX, INCY F95 INTERFACE SUBROUTINE ROT(N, X, INCX, Y, INCY, C, S) REAL :: C, S COMPLEX, DIMENSION(:) :: X, Y INTEGER :: N, INCX, INCY SUBROUTINE ROT_64(N, X, INCX, Y, INCY, C, S) REAL :: C, S COMPLEX, DIMENSION(:) :: X, Y INTEGER(8) :: N, INCX, INCY C INTERFACE #include <sunperf.h> void csrot(int n, complex *x, int incx, complex *y, int incy, float c, float s); void csrot_64(long n, complex *x, long incx, complex *y, long incy, float c, float s); PURPOSE csrot Apply a plane rotation, where the cos and sin (c and s) are real and the vectors x and y are complex. ARGUMENTS N (input) On entry, N specifies the number of elements in the vector. N must be at least one for the subroutine to have any visible effect. Unchanged on exit. X (input/output), dimension (1+(N-1)*abs(INCX)) On entry, the incremented array X must contain the vector x. On exit, X is overwritten by the updated vector x. INCX (input) On entry, INCX specifies the increment for the elements of X. INCX must not be zero. Unchanged on exit. Y (input/output), dimension (1+(N-1)*abs(INCY)) On entry, the incremented array Y must contain the vector y. On exit, Y is overwritten by the updated vector y. INCY (input) On entry, INCY specifies the increment for the elements of Y. INCY must not be zero. Unchanged on exit. C (input) On entry, the cosine. Unchanged on exit. S (input) On entry, the sin. Unchanged on exit. 7 Nov 2015 csrot(3P)
