Vectorization MATLAB sum equation snippet

Question

I am new to MATLAB, and would like to understand how we can vectorize below snippet, or how can i do it efficiently:

sum=0;
for i = 1:50
   sum=sum+i;
end

sum is also the name of an internal function of MATLAB. Try to avoid such variable names, as in your example you couldn't use the sum function after running this code (until clearing the sum variable) — hbaderts

sum(1:50)

The above statement initializes a vector of length 50 starting from 1 to 50 (with increments of length 1), and then calls MATLAB's sum function on it, returning the sum of all elements in the vector.

You can use sum native function:

total = sum(1:50);
