Is my matlab code for the sinc signal below correct.

I want to create and plot the signal equation below in matlab. The Coefficients ak are uniformly distributed in [−1, 1]. c is a constant.
![](https://www.mathworks.com/matlabcentral/answers/uploaded_files/1145865/image.png)
Here is my code:
%************ Variable declaration******************
t = -20:0.1:20;
p = -10:1:10
data = 0;
signal = zeros(1,length(t)); %for spped allocations
c = 25 % constant
ak = -1 + 2*rand(1,21); % numbers in the interval (a,b) with the formula r = a + (b-a).*rand(N,1).
count = 1;
%********************************************************************************************
for i = t
for k = p
data = data + c*ak(k+11)*sinc(i-k);
end
signal(counter) = data;
counter = counter + 1;
end
plot(t,signal);
Thanks in advance.

end
signal(i) = c*data;
end
plot(t,signal)
