hi

Basically I'm new to Matlab and i need to show that the 4 column vectors:

p=[4;3;-1;2;1], q=[-4;7;-9;0;3], r=[2;3;-2;0;1], s=[0;2;-2;3;1]

( ; means that the next number is on a new line..column vector...)

I need to show these are linearly dependant by solving the vector equation:

c1*p+c2*q+c3*r+c4*s=0

Does anyone know the shortest way to solve this using Matlab?
