NAME 💅

BLAS/SRC/zgeru.f — okay bestie, this is the BLAS/SRC/zgeru.f(3) page from the Library Functions Manual, and it's all about the ZGERU routine. No cap.

SYNOPSIS ✨

Functions/Subroutines 🦋

  • subroutine zgeru (m, n, alpha, x, incx, y, incy, a, lda) — ZGERU, the main character.

🌸 Function/Subroutine Documentation 🌸

   subroutine zgeru (integer m, integer n, complex*16 alpha, complex*16,
       dimension(*) x, integer incx, complex*16, dimension(*) y, integer incy,
       complex*16, dimension(lda,*) a, integer lda)

ZGERU. That's the vibe. 💜

Purpose ✨

ZGERU 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 — 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*16. On entry, ALPHA specifies the scalar alpha.
  • X — X is COMPLEX*16 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*16 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*16 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 ).
