how to solve this equation in matlab??

3x-2y+4=0

-x+2y -3=0

Answer 1

[Torsten]

A = [3 0 -2;-1 2 0];
b = [-4;3];
sol_inhomogen = A\b;
sol_homogen = null(A);
sol = @(lambda) sol_inhomogen + lambda*sol_homogen

sol = function_handle with value:
    @(lambda)sol_inhomogen+lambda*sol_homogen

%E.g.
sol(1)

ans = 3×1

-0.7988 1.1006 0.8018

A*sol(1)-b

ans = 2×1

1.0e-14 * -0.1776 0
