💅 SGER 💅

Okay so this gem is from the Library Functions Manual page for /home/abui...SRC/sger.f(3). It’s giving “rank-1 update but make it iconic,” and honestly? Obsessed. 🫶

✨ SYNOPSIS ✨

Functions/Subroutines

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

SGER — yes bestie, that’s the whole name, and it ate. 🎀

🦋 Function/Subroutine Documentation 🦋

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

SGER

💖 Purpose 💖

Bestie. Listen. SGER 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. The way that’s literally the whole vibe. 💅

🌈 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 REAL. On entry, ALPHA specifies the scalar alpha.
• X — X is REAL 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 REAL 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 REAL 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 ).
