How to solve the system of equations that the number of variable is fewer than the number of equations. for example:
x + y + 2z = 0,
2x + y -z = 0.
the result is
x = 3t,
y=-5t,
z=t.(t is parameter)
thanks you very much.

Or numerically,
null([1 1 2; 2 1 -1])

sol=solve('x + y + 2*z = 0','2*x + y -z = 0','x','y')
x=sol.x
y=sol.y
