💖 NAME 💖

bestie, the name is literally TESTING/LIN/crzt02.f 💅

✨ SYNOPSIS ✨

🫶 Functions/Subroutines 🫶

  • real function crzt02 (m, n, af, lda, tau, work, lwork) — CRZT02

🌸 Function/Subroutine Documentation 🌸

okay so here’s the exact signature, no cap:

   real function crzt02 (integer m, integer n, complex, dimension( lda, * ) af,
       integer lda, complex, dimension( * ) tau, complex, dimension( lwork )
       work, integer lwork)

CRZT02 is the main character here 👑

🎀 Purpose 🎀

CRZT02 returns

|| I - Q'*Q || / ( M * eps)

where the matrix Q is defined by the Householder transformations generated by CTZRZF. 🦋

🧚 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). 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. 🔥
