🌸 BLAS/SRC/sger.f(3) 🌸

Okay bestie, welcome to the BLAS/SRC/sger.f page from the Library Functions Manual. It's giving classic LAPACK, and SGER is here to do a rank 1 operation with main character energy. Let's get into it. ✨💅

💖 NAME 💖

BLAS/SRC/sger.f

---

✨ SYNOPSIS ✨

🎀 Functions/Subroutines 🎀

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

---

🫶 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

Okay so 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. That's 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 ).
