BLAS/SRC/csrot.f(3)

💖 NAME

Okay bestie, welcome to BLAS/SRC/csrot.f(3) from the Library Functions Manual. This page is for BLAS/SRC/csrot.f, aka the csrot subroutine page, and it's lowkey iconic: complex vectors, real cos and sin, all the rotation vibes. ✨

✨ SYNOPSIS

🫶 Functions/Subroutines

   subroutine csrot (n, cx, incx, cy, incy, c, s)

• This one is CSROT, no cap.

🦋 Function/Subroutine Documentation

   subroutine csrot (integer n, complex, dimension( * ) cx, integer incx,
       complex, dimension( * ) cy, integer incy, real c, real s)

CSROT

🌸 Purpose

CSROT applies a plane rotation, where the cos and sin (c and s) are real and the vectors cx and cy are complex. jack dongarra, linpack, 3/11/78.

💅 Parameters

• N — N is INTEGER. On entry, N specifies the order of the vectors cx and cy. N must be at least zero.
• CX — CX is COMPLEX array, dimension at least ( 1 + ( N - 1 )*abs( INCX ) ). Before entry, the incremented array CX must contain the n element vector cx. On exit, CX is overwritten by the updated vector cx.
• INCX — INCX is INTEGER. On entry, INCX specifies the increment for the elements of CX. INCX must not be zero.
• CY — CY is COMPLEX array, dimension at least ( 1 + ( N - 1 )*abs( INCY ) ). Before entry, the incremented array CY must contain the n element vector cy. On exit, CY is overwritten by the updated vector cy.
• INCY — INCY is INTEGER. On entry, INCY specifies the increment for the elements of CY. INCY must not be zero.
• C — C is REAL. On entry, C specifies the cosine, cos.
• S — S is REAL. On entry, S specifies the sine, sin.
