Hello
I have a set of equations and I want to solve using matrix system. Please have a lppk at the example
aV1=bV2+cV3
500V1^2+p1-230V2^2+p2=0
500V1^2+p1-230V3^2+p2=0
solving for unknowns i.e V1,V2,V3.
How to solve such a system using matrixes. Please Guide!!!
Regards

Two of the three equations are non-linear. You cannot solve these with some simple matrix operations. Take a pencil and a paper and calculate the solution yourself. It is not so hard. If you look closely at the second and third equation, you find out that V2 = V3 or V2 = -V3.

Hi...Thanks for replying. Its not about 3 equations. My system of equations consists of 14 equations out of which 7 equations are linear and 7 are non linear. Any guidance is appriciated.
