SQRT15(3)

💅 SQRT15(3) 💅

okay bestie, welcome to the LAPACK Library Functions Manual page for SQRT15 — it's giving "matrix generator with full or deficient rank and various norms," and we're gonna keep every single detail, fr fr. 🫶

🌸 NAME 🌸

/home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/TESTING/LIN/sqrt15.f

That's the whole name, no cap. It's the SQRT15 source file, and yes the path is doing the absolute most. 😭

✨ SYNOPSIS ✨

Functions/Subroutines

subroutine SQRT15 (scale, rksel, m, n, nrhs, a, lda, b, ldb, s, rank,
           norma, normb, iseed, work, lwork)

SQRT15

🎀 Function/Subroutine Documentation 🎀

subroutine SQRT15 (integer scale, integer rksel, integer m, integer n,
       integer nrhs, real, dimension( lda, * ) a, integer lda, real, dimension(
       ldb, * ) b, integer ldb, real, dimension( * ) s, integer rank, real
       norma, real normb, integer, dimension( 4 ) iseed, real, dimension( lwork
       ) work, integer lwork)

SQRT15

💖 Purpose 💖

SQRT15 generates a matrix with full or deficient rank and of various norms. That's the whole vibe. ✨

🧚 Parameters 🧚

• SCALE — SCALE is INTEGER. SCALE = 1: normally scaled matrix. SCALE = 2: matrix scaled up. SCALE = 3: matrix scaled down. pick your scaling era 💅
• RKSEL — RKSEL is INTEGER. RKSEL = 1: full rank matrix. RKSEL = 2: rank-deficient matrix. rank drama, choose wisely 😌
• M — M is INTEGER. The number of rows of the matrix A.
• N — N is INTEGER. The number of columns of A.
• NRHS — NRHS is INTEGER. The number of columns of B.
• A — A is REAL array, dimension (LDA,N). The M-by-N matrix A.
• LDA — LDA is INTEGER. The leading dimension of the array A.
• B — B is REAL array, dimension (LDB, NRHS). A matrix that is in the range space of matrix A.
• LDB — LDB is INTEGER. The leading dimension of the array B.
• S — S is REAL array, dimension MIN(M,N). Singular values of A.
• RANK — RANK is INTEGER. number of nonzero singular values of A.
• NORMA — NORMA is REAL. one-norm of A.
• NORMB — NORMB is REAL. one-norm of B.
• ISEED — ISEED is integer array, dimension (4). seed for random number generator.
• WORK — WORK is REAL array, dimension (LWORK).
• LWORK — LWORK is INTEGER. length of work space required. LWORK >= MAX(M+MIN(M,N),NRHS*MIN(M,N),2*N+M).
