When I try to run the CPF from 0 load and generation to the target case, I get following errors and warnings: step 1 : lambda = NaN, corrector did not converge in 10 iterations NaN's cannot be converted to logicals. Error in printpf (line 175) nzld = find((bus(:, PD) | bus(:, QD)) & bus(:, BUS_TYPE) ~= NONE); Error in runcpf (line 392) printpf(results, 1, mpopt); Error in Wildpoldsried_Extraction (line 236) results = runcpf(mpcbase, mpctarget); Warnings: Warning: Matrix is singular to working precision. > In newtonpf at 89 In runcpf at 203 In Wildpoldsried_Extraction at 236 Warning: Matrix is singular to working precision. > In cpf_predictor at 71 In runcpf at 249 In Wildpoldsried_Extraction at 236 Kindly let me know if you guys have any idea on how to address these issues.
