Solving Problem of Load flow analysis via using MATLAB?

Solving Problem of Load flow analysis via using MATLAB that has the one-line diagram of a simple three-bus power system with generation at bus 1. The voltage at bus 1 is V1 = 1 angle (0) pu. The scheduled load on buses 2 and 3 are marked on the diagram. Line impedance are marked in pu among (bus 1 & bus 2 = j1/30, bus 2 & bus 3 = j0.05, and bus 3 & bus 1=j0.0125) on a 100MVA base. Write a MATLAB program based on GS method and initial estimates of V2(0) = 1.0 + j0 and V3(0) = 1.0 + j0, determine V2 if (P2=400 MW & Q2=270Mvar) and V3.if (P3=300MW & Q3=320 Mvar)
