I have matrix with elements have small values. I am taking product of some elements of matrix for 100 times. If I take matrix 10*10 then it shows output but when I take matrix 100*100 then it shows 0. I think it shows 0 because product appears very small value. so how to take product so this small value should display.

help format
Specifically, I'd suggest one of these:
format long g
format short g

A = rand(5); %start with your standard floating point number
Asym = sym(A); %convert them to symbolic
B = Asym .^ 500; %raise them individually to the 500th power
num_digits = 50; %number of digits you want to see the result to
vpa(B, num_digits)
