ZGERC(3)

✨ ZGERC ✨

okay bestie, so this one's a BLAS girlie and she lives at:

/home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/BLAS/SRC/zgerc.f

it's a zgerc.f(3) situation, she's from the Library Functions Manual, and honestly? she ate. 💅

🌸 SYNOPSIS 🌸

Functions/Subroutines

subroutine ZGERC (m, n, alpha, x, incx, y, incy, a, lda)

ZGERC 🫶 (yes that's her name, yes she's iconic)

---

🦋 Function/Subroutine Documentation 🦋

subroutine ZGERC (integer m, integer n, complex*16 alpha, complex*16,
    dimension(*) x, integer incx, complex*16, dimension(*) y, integer incy,
    complex*16, dimension(lda,*) a, integer lda)

ZGERC 🎀

💖 Purpose 💖

!>
!> ZGERC  performs the rank 1 operation
!>
!>    A := alpha*x*y**H + A,
!>
!> where alpha is a scalar, x is an m element vector, y is an n element
!> vector and A is an m by n matrix.
!>

so like, she does a rank 1 operation — that's the whole vibe. alpha is a scalar, x is an m element vector, y is an n element vector, A is an m by n matrix, and she goes ahead and does

A := alpha*x*y**H + A

no cap, that's literally it. 🌟

🌈 Parameters 🌈

• M — ok so M is INTEGER. on entry, M specifies the number of rows of the matrix A. and like, M must be at least zero — bestie, don't come in here with negative rows, that's not the move 🙈
• N — N is INTEGER. on entry, N specifies the number of columns of the matrix A. N must be at least zero too. same energy, same rules 💀
• ALPHA — ALPHA is COMPLEX*16. on entry, ALPHA specifies the scalar alpha. she's the little multiplier bestie, main character energy ✨
• X — X is COMPLEX*16 array, dimension at least ( 1 + ( m - 1 )*abs( INCX ) ). before entry, the incremented array X must contain the m element vector x. put some respect on her 🫶
• INCX — INCX is INTEGER. on entry, INCX specifies the increment for the elements of X. and INCX must not be zero — like, literally do not. that's a vibe check she will fail 😭
• Y — Y is COMPLEX*16 array, dimension at least ( 1 + ( n - 1 )*abs( INCY ) ). before entry, the incremented array Y must contain the n element vector y. the other half of the iconique duo 💜
• INCY — INCY is INTEGER. on entry, INCY specifies the increment for the elements of Y. INCY must not be zero. periodt. 💅
• A — A is COMPLEX*16 array, dimension ( LDA, N ). before entry, the leading m by n part of the array A must contain the matrix of coefficients. on exit, A is overwritten by the updated matrix. she gets replaced, it's giving makeover montage 🧚✨
• LDA — LDA is INTEGER. on entry, LDA specifies the first dimension of A as declared in the calling (sub) program. LDA must be at least max( 1, m ). read it and weep, that's the floor 🔥

ok so she's a Level 2 Blas routine, written way back on 22-October-1986 by:

• Jack Dongarra, Argonne National Lab.
• Jeremy Du Croz, Nag Central Office.
• Sven Hammarling, Nag Central Office.
• Richard Hanson, Sandia National Labs.

1986 and she's STILL serving. legends only. 🌟💀 (affectionate)
