WebNov 22, 2015 · This is a very common indexing problem. Simply shifting your index by 1 can solve it. You'll just need to remember that now your d (1) is the old d (0) ( or say, the d (0) you see in math text). The math remains the same, you just index them differently. n = 15; t = -5:5; d = zeros (1,n+1); % Give d one more element. http://matlabmarina.com/pdf/matlab%20marina%20differentiation%20primer.pdf
