Why doesn't it work ? Please help

Hey!

I need to write this function , but i have tried it and it doesn't work.

Where am I wrong ?

The if function does not work like that.

You should try something like:

dt=0.01;
t=4;
T=0:dt:t;
p=zeros(size(T));
for i=1:length(T)
if T(i)>0 & T(i)<t/4
p(i)=sin(pi*T(i));
elseif T(i)>t/2 & T(i)<3*t/4
p(i)=1;
end
end
plot(T,p)

Thank you !

I will try

Answer 1

dt = 0.01; 
t = 4; 
T = 0:dt:t; 
% First Quarter 
r1 = 0:dt:t/4  ;
p1 = sin(pi.*r1)  ; 
plot (r1,p1) 
% Define second Quarter here and append it to the above

Hey !

I tried this and the second quarter didn't work

clear
close all
clc



dt = 0.01; 
t = 4; 
T = 0:dt:t; 


% First Quarter 
r1 = 0:dt:t/4  ;
p1 = sin(pi.*r1)  ; 

figure(1)
plot (r1,p1)
hold on



% Second Quarter

r2 = t/4:dt:t/2
p2 = 0;
y = [r2 , p2]
figure(2)
plot(y)

hold off

[VBBV]

% Second Quarter
r2 = t/4:dt:t/2
p2 = zeros(size(r2));
y = [p1 , p2]
figure(2)
plot([r1 r2],y)

Try it as above
