I unable to run my program.Please help me...

y=[repmat(0,1,7840),repmat(1,1,1317),repmat(2,1,239),repmat(3,1,42),repmat(4,1,14),repmat(5,1,4),repmat(6,1,4),repmat(1,1,1)] 
n=length(y)
k=tabulate(y)
x=y(1)
syms f j
f =@(x,r,d,j) (factorial(x)/(factorial(x-j)*factorial(j)))*((-1)^j)*((d+r+j+1)/((d+r+j)^2))

s1=symsum(f,j,0,x)

custlogpdf =@(x,d,r) log(factorial(r+x-1)/(factorial(x)*factorial(r-1)))+ log(s1); 

phat = mle(x,'logpdf',custlogpdf, 'start',[0.4,5,2,1])

"Error: File: imreader.m Line: 8 Column: 81 Unbalanced or unexpected parenthesis or bracket."

What part of the error message gives you trouble? Check your parentheses.

 custlogpdf =@(x,d,r) log(factorial(r+x-1)/(factorial(x)*factorial(r-1))+ log(s1));

Thanks for your help... I corrected the bracket but my error is in last line of my program...(i.e.,)

phat = mle(x,'logpdf',custlogpdf, 'start',[0.4,5,2,1])

I dont have the symbolic math toolbox.

What's the error message?
