Plotting frequency with different vector error

I am trying to plot a frequency graph with the center at the origin but I keep getting the error that the two vectors are different lengths. Is there anyway to fix this?

What input are you using? When I tried in R2020a on Mac and used 'hello' as the ASCII input, I had no problem.

Hi,
To get the desired shift so that the graph is symmetric about the origin, you can make the following changes in your code where you plot the ‘freq’ variable:
sz = length(freq)/2;
k = [-sz:-1,1:sz];
plot(k,abs(freq));
