%Develop a function in MatLab to

%Check the function with the function in Matlab.
%Develop a function. Don't use loop.
%Implement function with matrices.
%To test function using following signals.
%a)Aperiodic signal
%x[n]={0,1,2,3,4,3,2,1,0,0,0,0}
x=[0 1 2 3 4 3 2 1 0 0 ]
l=length(x)
disp('array initialized with zero and length l')
for k=1:10
xk(k)=0;
for n=1:10
xk(k)=xk(k)+x(n)*k;
end
end
disp('displaying final transform')
disp(xk)
%function [Xk] = dft(xn)
%x=[0 1 2 3 4 3 2 1 0 0 ]
%len = length(xn);
%w = 2*pi*linspace(0,1-1/len,len);
%Xk = exp(-1j*w'*(n-1))*xn';
