Plot a rectangular Pulse from -1 to 1

What can be the generalized code for this? I need a generalized code where the output asks me to enter the time axis and range and amplitude

t1=-2:0.01:-1; %time axis
t2=-1:0.01:1; %time axis 
t3=1:0.01:2; %time axis
t=[t1 t2 t3]; 
x1=zeros(size(t1)); %plotting 
x2=ones(size(t2));
x3=zeros(size(t3));
x=[x1 x2 x3];
plot(t,x);

t=input(); %t=[t1(start,end) t2(start,end) t3(start,end)]; eg:[-2 -1 -1 1 1 2]

number=input(); %enter number of points in interval t1,t2,t3

amplitude=input();

x1=zeros(number); %plotting

x2=amplitude*ones(number);

x3=zeros(number);

x=[x1 x2 x3];

tim=[linspace(t1(1),t1(2),number) linspace(t1(3),t1(4),number) linspace(t1(5),t1(6),number) ];

plot(tim,x);

This is what the error I'm getting after using your code. Kindly Help me.

input() takes a string, not a bunch of numerical variables with no multiplication sign between them. Again, a string, not numbers.

Ok. I hoped of some conversion from string to array but realized it doesn't work so changed the code to do it myself.

This just an example , you have to repeat according to your code requirements :

prompt = 'Enter the vector t1 ';
t1 = input(prompt);

Answer 2

% the syntax for taking input t eg:[-2 -1 1 2] =>t1=[-2,-1 ], t2=[-1 1], t3=[1 2].

%I was sleepy earlier so didn't run the code.

%code , don't edit anything as its already running well tested myself.

t=input("Enter the limit for axis : ",'s'); 
t1=str2num(t); %To get the array for that input string
number=input("enter number of points in interval t1,t2,t3 : "); %enter number of points in interval t1,t2,t3
amplitude=input("Enter the amplitude of square wave : ");
x1=zeros(number); %plotting 
x2=amplitude*ones(number);
x3=zeros(number);
x=[x1 x2 x3];
tim=[linspace(t1(1),t1(2),number) linspace(t1(2),t1(3),number) linspace(t1(3),t1(4),number) ]; %The time axis
plot(tim,x);
title("Rectangulat plot");
xlabel("time");
ylabel("Amplitude");

[SHIVAM KUMAR]

This is how it runs.
