💖 SBDT02(3) — Library Functions Manual 💖

okay so bestie, welcome to the glowed-up page for SBDT02(3). It's a Library Functions Manual entry, and the main-character file is serving path realness below. 🫶✨ iykyk.

✨ NAME ✨

The star of the show is this file path, no cap: /home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/TESTING/EIG/sbdt02.f

🦋 SYNOPSIS 🦋

🌈 Functions/Subroutines 🌈

       subroutine SBDT02 (m, n, b, ldb, c, ldc, u, ldu, work, resid)
           SBDT02

🎀 Function/Subroutine Documentation 🎀

   subroutine SBDT02 (integer m, integer n, real, dimension( ldb, * ) b,
       integer ldb, real, dimension( ldc, * ) c, integer ldc, real, dimension(
       ldu, * ) u, integer ldu, real, dimension( * ) work, real resid)
       SBDT02

✨ Purpose ✨

bestie, SBDT02 tests the change of basis C = U**H * B by computing the residual:

RESID = norm(B - U * C) / ( max(m,n) * norm(B) * EPS ),

where B and C are M by N matrices, U is an M by M orthogonal matrix, and EPS is the machine precision. slay. 💅

💅 Parameters 💅

• M — M is INTEGER. The number of rows of the matrices B and C, and the order of the matrix Q.
• N — N is INTEGER. The number of columns of the matrices B and C.
• B — B is REAL array, dimension (LDB,N). The m by n matrix B.
• LDB — LDB is INTEGER. The leading dimension of the array B. LDB >= max(1,M).
• C — C is REAL array, dimension (LDC,N). The m by n matrix C, assumed to contain U**H * B.
• LDC — LDC is INTEGER. The leading dimension of the array C. LDC >= max(1,M).
• U — U is REAL array, dimension (LDU,M). The m by m orthogonal matrix U.
• LDU — LDU is INTEGER. The leading dimension of the array U. LDU >= max(1,M).
• WORK — WORK is REAL array, dimension (M).
• RESID — RESID is REAL. RESID = norm(B - U * C) / ( max(m,n) * norm(B) * EPS ),
