i am defining a new function for generating unit sample sequences x(n)=delta(n-n0); n1<=n<=n2 i am proceeding in the follwing way .But some how i am getting error as not enough arguments at line n=[n1,n2];Therefore i am unable to define function.

i am defining a new function for generating unit sample sequences

x(n)=delta(n-n0); n1<=n<=n2

i am proceeding in the follwing way .But some how i am getting error as not enough arguments at line

n=[n1,n2];

Therefore i am unable to define function.

function [ x,n ] = impseq(n0,n1,n2)
% generates x(n)=delta(n-n0);n1<=n<=n2
% [ x,n ] = impseq(n0,n1,n2)
n=[n1,n2];
x=[(n-n0)==0];
end

[Azzi Abdelmalek]

save your function as impseq.m then call it in Windows Command

n1=2;
n2=10;
n0=5;
[x,n ] = impseq(n0,n1,n2)

[Pranali]

I followed all the steps given by you ....but still i am gettiing the same error.ie not enough input arguments........which input arguments are less......that is not clear to me........

[Mohammed Akthar kazi]

Don't execute the script file in which you have written your function.save your function as impseq.m and call this function from command window by typing n1=-5; n2=5; n0=0; n=n1:n2; [x,n]=impseq(n0,n1,n2) ;

in your code change n=[n1,n2] to n=[n1:n2];

[AUONKAR]

n=(-5:5);
x=n.*impseq(-3,-5,5)-impseq(4,-5,5);
y=2*impseq(-2,-5,5)-impseq(4,-5,5);

subplot(121);
stem(n,x);
xlabel('input')
ylabel('output')
title('1st plot')
grid on
hold on

subplot(122);
stem(n,y);
xlabel('input')
ylabel('output')
title('2nd plot')
grid on
hold on

function [x]=impseq (n0,n1,n2)
    n= [n1:n2];
    x=[(n-n0)==0];
end
