CCHKQP3RK

🌸 Purpose 🌸

!>
!> CCHKQP3RK tests CGEQP3RK.
!>

Short version: CCHKQP3RK is literally here to test CGEQP3RK. That's the assignment, and it ate. 💅

🎀 Parameters 🎀

Okay, parameter parade time — every single one is below, bestie. 🫶

• DOTYPE — DOTYPE is LOGICAL array, dimension (NTYPES). The matrix types to be used 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 — NM is INTEGER. The number of values of M contained in the vector MVAL. ✨
• MVAL — MVAL is INTEGER array, dimension (NM). The values of the matrix row dimension M. 🦋
• NN — NN is INTEGER. The number of values of N contained in the vector NVAL. 🌸
• NVAL — NVAL is INTEGER array, dimension (NN). The values of the matrix column dimension N. 🎀
• NNS — NNS is INTEGER. The number of values of NRHS contained in the vector NSVAL. 💖
• NSVAL — NSVAL is INTEGER array, dimension (NNS). The values of the number of right hand sides NRHS. 🫶
• NNB — NNB is 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 — NBVAL is INTEGER array, dimension (NNB). The values of the blocksize NB. 🔥
• NXVAL — NXVAL is INTEGER array, dimension (NNB). The values of the crossover point NX. ⭐
• THRESH — THRESH is 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. 💀
• A — A is COMPLEX array, dimension (MMAX*NMAX) where MMAX is the maximum value of M in MVAL and NMAX is the maximum value of N in NVAL. 🌈
• COPYA — COPYA is COMPLEX array, dimension (MMAX*NMAX). 💜
• B — B is COMPLEX array, dimension (MMAX*NSMAX) where MMAX is the maximum value of M in MVAL and NSMAX is the maximum value of NRHS in NSVAL. 🍓
• COPYB — COPYB is COMPLEX array, dimension (MMAX*NSMAX). 🧚
• S — S is REAL array, dimension (min(MMAX,NMAX)). 💅
• TAU — TAU is COMPLEX array, dimension (MMAX). ✨
• WORK — WORK is COMPLEX array, dimension (max(M*max(M,N) + 4*min(M,N) + max(M,N))). 💜
• RWORK — RWORK is REAL array, dimension (4*NMAX). 🦋
• IWORK — IWORK is INTEGER array, dimension (2*NMAX). 🌸
• NOUT — NOUT is INTEGER. The unit number for output. 🎀
