💖 SRC/slag2d.f(3) 💖

okay bestie, welcome to the Library Functions Manual page for SRC/slag2d.f(3) — it’s giving “tiny but important linear algebra helper” energy, and we’re gonna get into every single detail. 🫶

✨ NAME ✨

SRC/slag2d.f

🌸 SYNOPSIS 🌸

🧚 Functions/Subroutines

• subroutine slag2d (m, n, sa, ldsa, a, lda, info) — SLAG2D converts a single precision matrix to a double precision matrix.

🦋 Function/Subroutine Documentation 🦋

subroutine slag2d signature, no cap

   subroutine slag2d (integer m, integer n, real, dimension( ldsa, * ) sa,
       integer ldsa, double precision, dimension( lda, * ) a, integer lda,
       integer info)

SLAG2D converts a single precision matrix to a double precision matrix. ✨

---

🔥 Purpose 🔥

SLAG2D converts a SINGLE PRECISION matrix, SA, to a DOUBLE PRECISION matrix, A. Note that while it is possible to overflow while converting from double to single, it is not possible to overflow when converting from single to double. This is an auxiliary routine so there is no argument checking. 🫣

🎀 Parameters 🎀

• M — M is INTEGER; the number of lines of the matrix A. M >= 0.
• N — N is INTEGER; the number of columns of the matrix A. N >= 0.
• SA — SA is REAL array, dimension (LDSA,N); on entry, the M-by-N coefficient matrix SA.
• LDSA — LDSA is INTEGER; the leading dimension of the array SA. LDSA >= max(1,M).
• A — A is DOUBLE PRECISION array, dimension (LDA,N); on exit, the M-by-N coefficient matrix A.
• LDA — LDA is INTEGER; the leading dimension of the array A. LDA >= max(1,M).
• INFO — INFO is INTEGER; = 0: successful exit.
