How do I create a square wave using 'zeros' and 'ones' functions?
Show older comments
Here is my code so far.
clear all; close all; clc;
incrm = 0.01;
T0 = 2;
W0 = pi;
t = 0:0.01:10;
xt = ???????????????
plot(t,xt)
hold on
xlim([0,10]);
ylim([0,1]);
xlabel('t');
ylabel('xt');

t = 0:0.01:10;
x=ones(1,numel(t)) %add this
x(t>=1 & t<2 | t>=3 & t<4 | t>=5 & t<=6 | t>=7 & t<=8 | t>=9 & t<=10 )=0 %and this
plot(t,x) % if you add t+pi horizontal shift or t-pi
xlim([0,10]);
ylim([0,1]);
xlabel('t');
ylabel('xt');

dude ! change
x(t>=1 & t<2 | t>=3 & t<4 | t>=5 & t<=6 | t>=7 & t<=8 | t>=9 & t<=10 )=0
to this
xt(t>=1 & t<2 | t>=3 & t<4 | t>=5 & t<=6 | t>=7 & t<=8 | t>=9 & t<=10 )=0

x(t>=1 & t<2 | t>=3 & t<4 | t>=5 & t<=6 | t>=7 & t<=8 | t>=9 & t<=10 )=0 <----- it should be zero not one!!!
