function Calcularsolucin2ButtonValueChanged(app, event)

P = 50;

Q = 60;

C1 = 4;

C2 = 7;

K = 10;

a = app.a.Value;

b = app.b.Value;

x = linspace(0,1000);

y2 = K/(exp((K*x-K*C2))-b);

plot (app.Axes,y2,x,'r');

hold on;

y = linspace(0,1000);

x2 = K/(exp(K*y-K*C1)-a);

plot (app.Axes,x2,y,'b');

end

Try replacing the line assigning x2 with the following using ./ to get element by element division

y2 = K./(exp((K*x-K*C2))-b);
