CRZT02(3)

💖 CRZT02(3) 💖

manual name check: this one lives in the Library Functions Manual. okay bestie, it's giving tiny precise LAPACK routine energy, and we're gonna read every line. 🫶

💖 NAME 💖

/home/abuild/rpmbuild/BUILD/lapack-static-3.12.0-build/lapack-3.12.0/TESTING/LIN/crzt02.f

That's literally the whole NAME section — just the path, no extra tagline. Respect. 💅

🌈 SYNOPSIS 🌈

🦋 Functions/Subroutines 🦋

       real function CRZT02 (m, n, af, lda, tau, work, lwork)
           CRZT02

✨ Function/Subroutine Documentation ✨

Here's the full signature, copied exactly so your eyeballs can vibe-check it:

       real function CRZT02 (integer m, integer n, complex, dimension( lda, * ) af,
       integer lda, complex, dimension( * ) tau, complex, dimension( lwork )
       work, integer lwork)
       CRZT02

🎯 Purpose 🎯

okay so CRZT02 returns this exact thing:

!>
!> CRZT02 returns
!>      || I - Q'*Q || / ( M * eps)
!> where the matrix Q is defined by the Householder transformations
!> generated by CTZRZF.
!>

So yes: it's the || I - Q'*Q || / ( M * eps) ratio, and Q is defined by the Householder transformations generated by CTZRZF. Slay. 💅

🌸 Parameters 🌸

• M — M is INTEGER; the number of rows of the matrix AF. 💖
• N — N is INTEGER; the number of columns of the matrix AF. 🦋
• AF — AF is COMPLEX array, dimension (LDA,N); this is the output of CTZRZF. ✨
• LDA — LDA is INTEGER; the leading dimension of the array AF. 🎀
• TAU — TAU is COMPLEX array, dimension (M); details of the Householder transformations as returned by CTZRZF. 🌈
• WORK — WORK is COMPLEX array, dimension (LWORK). 💜
• LWORK — LWORK is INTEGER; length of WORK array. LWORK >= N*N+N. 🔥
