How to plot graph from equation

clc

close all

clear all

syms T2 T3 T4 x4 x3 ;

x2 = [T2 ;T3 ;T4];

T1 = 303;

k = 10;

L = 3;

h = 10;

figure(1)

for x3 = [1 0.1 0.01 0.001]

x1 = [-2 1 0;1 -2 1;0 -1 1+x3];

equ = x2 == inv(x1)*[-100*(x3)^2-303; -100*(x3)^2; 100*(x3)^2+303*x3];

disp(equ)

plot(x3,equ,'b')

hold on

end

I wanna plot grah by x3 is x axis and T2 T3 T4 is y axis

I'm not sure what do you want, is it like this?

x3 = [1 0.1 0.01 0.001];
x2 = zeros(3,4);
for i=1:4
    x1 = [-2 1 0;1 -2 1;0 -1 1+x3(i)];
    x2(:,i) = inv(x1)*[-100*(x3(i))^2-303; -100*(x3(i))^2; 100*(x3(i))^2+303*x3(i)];
end

plot(x3,x2(1,:))
hold on
plot(x3,x2(2,:))
plot(x3,x2(3,:))
hold off
