Summation of Delta function on R2013b

I have an impulse response h(n) as mentioned below.Can someone please help me how to simulate this on MATLAB R2013b since I cannot get symsum(delta(k),k,0,N-1) to work on this version of MATLAB. If someone could please post a snippet that would be really helpful.

h(n) = (1/N)*(∑(k=0 to N-1)[delta(k)] where delta(k) is an unit impulse.

Answer 1

[Walter Roberson]

h = @(N) sum( dirac(0:N-1) )

This will be infinite for all non-negative N because it includes delta(k) where k = 0, and delta(0) is infinite.

Perhaps you are looking for

syms N K
h = symsum(dirac(k),k,0,N-1)

the result for which will display as

sum(dirac(k), k == 0..N - 1)

I tested these in R2013b.
