🎯 Purpose 🎯

CCHKQR tests CGEQRF, CUNGQR and CUNMQR. Like, that's the whole assignment, bestie. 💖

📝 Parameters 📝

• DOTYPE (LOGICAL array, dimension (NTYPES)) — the matrix types to use for testing. Matrices of type j (for 1 <= j <= NTYPES) are used for testing if DOTYPE(j) = .TRUE.; if DOTYPE(j) = .FALSE., then type j is not used. 🧪
• NM (INTEGER) — the number of values of M contained in the vector MVAL. 🔢
• MVAL (INTEGER array, dimension (NM)) — the values of the matrix row dimension M. 📏
• NN (INTEGER) — the number of values of N contained in the vector NVAL. 🔢
• NVAL (INTEGER array, dimension (NN)) — the values of the matrix column dimension N. 📐
• NNB (INTEGER) — the number of values of NB and NX contained in the vectors NBVAL and NXVAL. The blocking parameters are used in pairs (NB,NX). 👯
• NBVAL (INTEGER array, dimension (NNB)) — the values of the blocksize NB. 🧱
• NXVAL (INTEGER array, dimension (NNB)) — the values of the crossover point NX. 🚦
• NRHS (INTEGER) — the number of right hand side vectors to be generated for each linear system. 🎯
• THRESH (REAL) — the threshold value for the test ratios. A result is included in the output file if RESULT >= THRESH. To have every test ratio printed, use THRESH = 0. 🚨
• TSTERR (LOGICAL) — flag that indicates whether error exits are to be tested. 🐛
• NMAX (INTEGER) — the maximum value permitted for M or N, used in dimensioning the work arrays. 📦
• A (COMPLEX array, dimension (NMAX*NMAX)) — here's your A array, bestie. 💎
• AF (COMPLEX array, dimension (NMAX*NMAX)) — the AF array. ✨
• AQ (COMPLEX array, dimension (NMAX*NMAX)) — the AQ array. 🦋
• AR (COMPLEX array, dimension (NMAX*NMAX)) — the AR array. 🌸
• AC (COMPLEX array, dimension (NMAX*NMAX)) — the AC array. 💅
• B (COMPLEX array, dimension (NMAX*NRHS)) — the B array. 🎀
• X (COMPLEX array, dimension (NMAX*NRHS)) — the X array. ⭐
• XACT (COMPLEX array, dimension (NMAX*NRHS)) — the XACT array. 🔥
• TAU (COMPLEX array, dimension (NMAX)) — the TAU array. 👑
• WORK (COMPLEX array, dimension (NMAX*NMAX)) — the WORK array. 🛠️
• RWORK (REAL array, dimension (NMAX)) — the RWORK array. 🌈
• IWORK (INTEGER array, dimension (NMAX)) — the IWORK array. 🧮
• NOUT (INTEGER) — the unit number for output. 📤
