This looks like a homework problem. If you have any questions ask your instructor or read the link below to get started:

How do I get help on homework questions on MATLAB Answers? - MATLAB Answers - MATLAB Central

Obviously we can't give you the full solution because you're not allowed to turn in our code as your own.

Some hints to get you started:

n = 5;
v = 1 : n

v = 1×5

1 2 3 4 5

denom = 1 ./ v

denom = 1×5

1.0000 0.5000 0.3333 0.2500 0.2000

x = 3;
num = x .^ v

num = 1×5

3 9 27 81 243

its not for an assignment, Im doing practice on my own and I cant figure out how to write the eqation in matlab and I learn best from examples

Here is it in more steps than needed just to show you each step involved.

% Call the function with x=10 and n=5
output = e(10, 5)

%-------------------------------------------------------------------
% function definition:
function output = e(x, numberOfTerms)
v = 0 : numberOfTerms
denom = factorial(v)
denom = 1 ./ denom
numerator = x .^ v
output = numerator ./ denom
output = sum(output)
end

format long g
syms x n m
result = symsum(x^n/factorial(n), n, 0, m)

result = 

limit(result, m, inf)

ans = 

result20 = subs(result, m, 20)

result20 = 

exp20 = subs(result20, x, sym(pi))

exp20 = 

exp20_numeric = double(exp20)

exp20_numeric = 
          23.1406926321509

exact = exp(sym(pi))

exact = 

exact_numeric = double(exact)

exact_numeric = 
          23.1406926327793

exact_numeric - exp20_numeric

ans =
