lookup function reads the data from a file
ybuild builds the Ybus matrix
TOF and SOLVE solves the Ax=b problem using simple substitution
HW51 actually builds the Jacobian and solves the load flow problem!
in 1995 Prof Gerald T Heydt did not believe that load flow analysis could be done in MATLAB. He recommended Fortran, passing the class depended a lot on the load flow project. I was younger then and I was familiar with MATLAB, so I took on the challenge. After a couple weeks of wrestling with it, I was able to solve it. By now this is probably legacy code! Enjoy!
