TESTING/LIN/dqrt13.f(3)

💅 NAME 💅

okay so bestie, this page is from the Library Functions Manual, and it’s all about TESTING/LIN/dqrt13.f — specifically the dqrt13 subroutine, and yes it’s giving matrix-generator main character energy. ✨

🦋 SYNOPSIS 🦋

🎀 Functions/Subroutines 🎀

here’s the callable subroutine vibe:

       subroutine dqrt13 (scale, m, n, a, lda, norma, iseed)
           DQRT13

🌸 Function/Subroutine Documentation 🌸

💖 subroutine dqrt13 💖

       subroutine dqrt13 (integer scale, integer m, integer n, double precision,
           dimension( lda, * ) a, integer lda, double precision norma, integer,
           dimension( 4 ) iseed)
           DQRT13

✨ Purpose ✨

DQRT13 generates a full-rank matrix that may be scaled to have large or small norm. 🫶

🍓 Parameters 🍓

• SCALE — SCALE is INTEGER
  • SCALE = 1: normally scaled matrix
  • SCALE = 2: matrix scaled up
  • SCALE = 3: matrix scaled down
• M — M is INTEGER; the number of rows of the matrix A.
• N — N is INTEGER; the number of columns of A.
• A — A is DOUBLE PRECISION array, dimension (LDA,N); the M-by-N matrix A.
• LDA — LDA is INTEGER; the leading dimension of the array A.
• NORMA — NORMA is DOUBLE PRECISION; the one-norm of A.
• ISEED — ISEED is integer array, dimension (4); seed for random number generator.
