BLAS/SRC/cgerc.f(3)

💖 NAME 💖

okay bestie, welcome to BLAS/SRC/cgerc.f(3), straight out of the Library Functions Manual ✨ This is the page for cgerc, and yes, it's giving main-character BLAS routine energy 💅

---

✨ SYNOPSIS ✨

🎀 Functions/Subroutines 🎀

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

CGERC — that's her, that's the routine 🫶

---

🌸 Function/Subroutine Documentation 🌸

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

CGERC — the whole signature, no cap 🔥

🎯 Purpose 🎯

CGERC 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. Obsessed with the clarity, honestly 🌟

🧮 Parameters 🧮

• M — M is INTEGER. On entry, M specifies the number of rows of the matrix A. M must be at least zero.
• N — N is INTEGER. On entry, N specifies the number of columns of the matrix A. N must be at least zero.
• ALPHA — ALPHA is COMPLEX. On entry, ALPHA specifies the scalar alpha.
• X — X is COMPLEX array, dimension at least ( 1 + ( m - 1 )*abs( INCX ) ). Before entry, the incremented array X must contain the m element vector x.
• INCX — INCX is INTEGER. On entry, INCX specifies the increment for the elements of X. INCX must not be zero.
• Y — Y is COMPLEX array, dimension at least ( 1 + ( n - 1 )*abs( INCY ) ). Before entry, the incremented array Y must contain the n element vector y.
• INCY — INCY is INTEGER. On entry, INCY specifies the increment for the elements of Y. INCY must not be zero.
• A — A is 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 — 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 ).

okay that's the whole page, bestie — LAPACK Version 3.12.0, source BLAS/SRC/cgerc.f(3), and the date tea is the 22-October-1986 write date (the footer itself has no date line) 🫶🎀
