Hi,
I have to generate a square wave like the one shown in the fig below. Can any one please indicate the appropriate code for that?
Thanks,

function [z t] = square(n1,n2)
% n1=2 give similar value
% n2=4 give this value
z=[];
t=1:1:n2
x= [];
for i=1:5
for t1= 0.01:0.01:n1
a=1
z=[z a];
x=[x t1]
end
for t2=n1+0.01:0.01:n2
a=-1
z=[z a];
x=[x t2]
end
t=1:0.01:n2;
x=1:0.01:n2;
plot(z);
end

How about repmat()? One of your toolboxes may also have a function.

It's basically the same, you just have finer x resolution so when plotted the slopes from low to high appear steeper. Either way, they're both square waves with instantaneous jumps, regardless of how they look while plotted.

thank your sir sir pl help how to generate a square wave without using any functions of matlab with basic functions only

% endCan it be done with this code ?
t = n*T:1:((n+1)*T);
%lengtht = length(t);
% Define x(t) and plot
if (mod(n,2) == 0)
%number is even
x = 1;
else
%number is odd
x = -1;
end
plot(x)
set(gcf, 'Units', 'Normalized', 'Outerposition', [0, 0, 1, 1]);

Please give the link to your source code so I can compare your MATLAB code to the original, which presumably is in pseudocode or another language.

The following square wave function can be used just like sin(x) providing a phase argument and duty-cycle and getting a signal in the range -1 to 1 accordingly.
function y = square(x, D)
r = mod(x/(2*pi), 1); % generate a ramp over every cycle
y = 1 - 2*(r > D); % output result from -1 to 1
end
