ZLAT2C(3)

💅 ZLAT2C: the triangular conversion bestie page 💅

okay so bestie, welcome to the zlat2c.f(3) page in the LAPACK Library Functions Manual — it's giving source-file identity moment, and we're gonna get through it with zero fear and maximum sparkle ✨. This is an auxiliary routine with main character energy, fr fr. 🦋

🌸 NAME 🌸

/home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/SRC/zlat2c.f

That's the whole NAME section, and honestly she ate: just the path, no notes. 💅

✨ SYNOPSIS ✨

🧚 Functions/Subroutines 🧚

       subroutine ZLAT2C (uplo, n, a, lda, sa, ldsa, info)
           ZLAT2C converts a double complex triangular matrix to a complex
           triangular matrix.

💫 Function/Subroutine Documentation 💫

subroutine ZLAT2C (character uplo, integer n, complex*16, dimension( lda, * ) a, integer lda, complex, dimension( ldsa, * ) sa, integer ldsa, integer info)

🎀 Purpose 🎀

ZLAT2C converts a COMPLEX*16 triangular matrix, SA, to a COMPLEX triangular matrix, A. That's the glow-up: double complex to complex, triangular to triangular. 💖

RMAX is the overflow for the SINGLE PRECISION arithmetic. ZLAT2C checks that all the entries of A are between -RMAX and RMAX. If not, the conversion is aborted and a flag is raised. 🚩

This is an auxiliary routine so there is no argument checking. Periodt. 💅

🍓 Parameters 🍓

• UPLO — UPLO is CHARACTER*1.
  • = 'U': A is upper triangular;
  • = 'L': A is lower triangular.
• N — N is INTEGER; the number of rows and columns of the matrix A. N >= 0.
• A — A is COMPLEX*16 array, dimension (LDA,N). On entry, the N-by-N triangular coefficient matrix A.
• LDA — LDA is INTEGER; the leading dimension of the array A. LDA >= max(1,N).
• SA — SA is COMPLEX array, dimension (LDSA,N). Only the UPLO part of SA is referenced. On exit, if INFO=0, the N-by-N coefficient matrix SA; if INFO>0, the content of the UPLO part of SA is unspecified.
• LDSA — LDSA is INTEGER; the leading dimension of the array SA. LDSA >= max(1,M). yes, it says M, bestie — iykyk, we are keeping the manpage's exact letter 💀
• INFO — INFO is INTEGER.
  • = 0: successful exit.
  • = 1: an entry of the matrix A is greater than the SINGLE PRECISION overflow threshold; in this case, the content of the UPLO part of SA in exit is unspecified.
