% FIRST SCRIPT. I NEED TO SHOW THE SAME GRAPHICS IN THE SAME IN BOTH SCRIPTS !!. PLEASE
clc
clear
CC = input ('Ingrese la COMPLIANCIA (cm3/cmH2O)DEL PULMON C = ');
C= CC/981;
subplot (2,2,1)
syms t
Q1 = 1
hold on
fplot(Q1,[0 1])
Q2 = t
fplot(Q2,[1 2])
Q3 = 2
fplot(Q3,[2 3])
axis([0 3 0 3])

% SCRIPT ABOUT THE FUNCTION
function [Q] = flujo (t)
t=0:0.01:3;
%Q = ((t>0)&(t<1)).*(3-2*t)+ ((t>=1)&(t<2)).*(3*t-6)+ ((t>=2)&(t<=3)).*(0);
Q = ((t>0)&(t<1)).*(1)+ ((t>=1)&(t<2)).*(t)+ ((t>=2)&(t<=3)).*(2);
% Q = ((t>0)&(t<1)).*(2*t)+ ((t>=1)&(t<2)).*(3)+ ((t>=2)&(t<=3)).*(3-t);
plot(t,Q)
grid on
axis([0 3 -4 4])
