TESTING/LIN/zrzt02.f(3)

🌸 NAME 🌸

Okay so this manual page is for TESTING/LIN/zrzt02.f(3) from the Library Functions Manual, and the main character is literally ZRZT02. We're about to read the whole thing together, bestie — no skimming, no cap. 🫶

✨ SYNOPSIS ✨

Functions/Subroutines

       double precision function zrzt02 (m, n, af, lda, tau, work, lwork)
           ZRZT02

🧚 Function/Subroutine Documentation 🧚

   double precision function zrzt02 (integer m, integer n, complex*16,
       dimension( lda, * ) af, integer lda, complex*16, dimension( * ) tau,
       complex*16, dimension( lwork ) work, integer lwork)
       ZRZT02

🎯 Purpose 🎯

ZRZT02 returns || I - Q'*Q || / ( M * eps) where the matrix Q is defined by the Householder transformations generated by ZTZRZF. That's the whole vibe, and it's iconic. 💅

🌈 Parameters 🌈

• M — M is INTEGER; the number of rows of the matrix AF. Row count, periodt. 🌈
• N — N is INTEGER; the number of columns of the matrix AF. Column count, slay. 💅
• AF — AF is COMPLEX*16 array, dimension (LDA,N); literally the output of ZTZRZF. Obsessed. ✨
• LDA — LDA is INTEGER; the leading dimension of the array AF. That's the leading-dim gig. 🎀
• TAU — TAU is COMPLEX*16 array, dimension (M); details of the Householder transformations as returned by ZTZRZF. iykyk. 🦋
• WORK — WORK is COMPLEX*16 array, dimension (LWORK). The work array, bestie. 🫶
• LWORK — LWORK is INTEGER; length of WORK array. LWORK >= N*N+N. Not me forgetting the inequality, periodt. 🔥

That's the whole page, bestie — source is TESTING/LIN/zrzt02.f(3), version is LAPACK Version 3.12.0, and the footer has no date, so we're leaving it iconic and mysterious. Byeee! 💖✨
