Solve System of Equations

I want to solve a system of equations of the form :

V=V*P -> (V(I-P)=0)

For example:

V=[x1,x2,x3]; %are the unknows P=[1,2,3;1,2,5;1,3,5]; %It's a matrix with constants.

[Kartik Katti]

for i=1:20 for j=1:20 for k=1:20 P=[1,2,3;1,2,5;1,3,5]; v=[i-1 j-1 k-1]; if (v-(v*P))==0; u=[i j k]; break else end end end end

This program is based on regression concept. Hope this works for you.

 I=eye(size(P));
 V=null( I - P.');
