BLAS/SRC/cdotu.f(3)

hey bestie 💖 welcome to the BLAS/SRC/cdotu.f(3) page — yes, that’s from the Library Functions Manual, and we’re about to make a complex dot product make sense. no cap.

✨ NAME ✨

BLAS/SRC/cdotu.f — the file that brings you cdotu, the complex dot-product icon. 👑

🌈 SYNOPSIS 🌈

🎀 Functions/Subroutines 🎀

• complex function cdotu (n, cx, incx, cy, incy) — CDOTU

🧚 Function/Subroutine Documentation 🧚

here’s the full signature, character-for-character:

complex function cdotu (integer n, complex, dimension(*) cx, integer incx,
    complex, dimension(*) cy, integer incy)

CDOTU

🌟 Purpose 🌟

okay so the purpose, verbatim from the source comments:

!>
!> CDOTU forms the dot product of two complex vectors
!>      CDOTU = X^T * Y
!>
!>

💅 Parameters 💅

• N — N is INTEGER; number of elements in input vector(s).
• CX — CX is COMPLEX array, dimension ( 1 + ( N - 1 )*abs( INCX ) ).
• INCX — INCX is INTEGER; storage spacing between elements of CX.
• CY — CY is COMPLEX array, dimension ( 1 + ( N - 1 )*abs( INCY ) ).
• INCY — INCY is INTEGER; storage spacing between elements of CY.
