Adding random numbers together

So I'm using this code

% Create a vector of 53 random #s and analyze them.
r = rand([53,1])
% The sum of all the random numbers
sum=sum(([53,1]))
disp(result)

But it doesn't seem to be working.

I'm new to ML

How do I find the sum (and product) of the random numbers?

Overwriting the function "sum" by a variable called "sum" also will lead to strange effects.

sum(r)
prod(r)

Answer 2

% Create a vector of 53 random #s and analyze them.
r = input('enter random number:');
r = rand([53,1])
% The sum of all the random numbers
b = cumsum(53,1)
disp(result)

Answer 3

% Author: Sean Walsh
% Create a vector of 53 random #s and analyze them.
r = rand([53,1]);
% The sum of all the random numbers
sum(r)
% The product of all the random numbers
prod(r)

This is what I wrote.

This is what came out.

>> lab0202

ans =

     27.0784

ans =

     2.1169e-21

>> clear
>> lab0202
K>> clear
>> lab0202

ans =

     27.7177

ans =

     6.1916e-21

It didn't list all 53?
