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.

% 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)

sum(r)
% The product of all the random numbers
prod(r)
This is what I wrote.
This is what came out.

It didn't list all 53?
