CGERU(3)

💅 CGERU(3) — Library Functions Manual ✨

okay so bestie, this is a whole BLAS page and it is lowkey iconic. It lives in the Library Functions Manual, and the vibe is "rank-1 update but make it cute." The exact source path is the NAME section, so let's go 💖

🌸 NAME 🌸

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

✨ SYNOPSIS ✨

🦋 Functions/Subroutines 🦋

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

and the name again, because the page says it: CGERU 🫶

🎀 Function/Subroutine Documentation 🎀

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

CGERU

💖 Purpose 💖

the exact purpose block is right here, no cap:

!>
!> CGERU  performs the rank 1 operation
!>
!>    A := alpha*x*y**T + 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.
!>

🌈 Parameters 🌈

• M — INTEGER. on entry, M tells you the number of rows of matrix A; and bestie, M must be at least zero.
• N — INTEGER. on entry, N tells you the number of columns of matrix A; N must be at least zero.
• ALPHA — COMPLEX. on entry, ALPHA is the scalar alpha. cute.
• X — COMPLEX array, dimension at least ( 1 + ( m - 1 )*abs( INCX ) ). before entry, the incremented array X must contain the m element vector x.
• INCX — INTEGER. on entry, INCX is the increment for the elements of X. INCX must not be zero.
• Y — COMPLEX array, dimension at least ( 1 + ( n - 1 )*abs( INCY ) ). before entry, the incremented array Y must contain the n element vector y.
• INCY — INTEGER. on entry, INCY is the increment for the elements of Y. INCY must not be zero.
• A — COMPLEX 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.
• LDA — INTEGER. on entry, LDA is the first dimension of A as declared in the calling (sub) program. LDA must be at least max( 1, m ).
