here I plot two graphs from four polynoms with dis code:

figure()
for i=1:length(nodos)-1
plot([nodos(i):0.01:nodos(i+1)],polyval([Mx(:,:,i)],[nodos(i):0.01:nodos(i+1)]),'-','LineWidth',2.5,'Color','b')
hold on   % Different colored lines
end
xlabel('Longitud de la Viga [m]') 
ylabel('Fuerza cortante[N]') 
yline(0)
figure()
for i=1:length(nodos)-1
    plot([nodos(i):0.01:nodos(i+1)],polyval([Vx(:,:,i)],[nodos(i):0.01:nodos(i+1)]),'-','LineWidth',2.5,'Color','b')
    hold all   % % Different colored lines
end
xlabel('Longitud de la Viga [m]') 
ylabel('Momento Flector [n*M]') 
yline(0)
