BLAS/SRC/dger.f(3)

💖 NAME 💖

BLAS/SRC/dger.f — ok so this is the LAPACK manual page for that file, bestie, and it's literally the home of DGER ✨

---

🌸 SYNOPSIS 🌸

Functions/Subroutines

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

---

🦋 Function/Subroutine Documentation 🦋

subroutine dger (integer m, integer n, double precision alpha, double
    precision, dimension(*) x, integer incx, double precision, dimension(*)
    y, integer incy, double precision, dimension(lda,*) a, integer lda)
DGER

✨ Purpose ✨

DGER 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. That's it, that's the whole serve 💅

🎀 Parameters 🎀

• M — this one's an INTEGER. On entry, M specifies the number of rows of the matrix A. M must be at least zero. no negative rows allowed, queen 🙈
• N — also an INTEGER. On entry, N specifies the number of columns of the matrix A. N must be at least zero.
• ALPHA — ALPHA is DOUBLE PRECISION. On entry, ALPHA specifies the scalar alpha. the main character scalar, fr fr ⭐
• X — X is a DOUBLE PRECISION 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. like, zero is not an option bestie 💀
• Y — Y is a DOUBLE PRECISION 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. same vibe check, same rule 🫶
• A — A is a DOUBLE PRECISION 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 a whole glow-up on the way out ✨
• 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 ).
