% Write a while loop that assigns summedValue with the sum of all values from 1 to userNum.
% Assume userNum is always greater than or equal to 1
function summedValue = SummationWithLoop(userNum)
% Summation of all values from 1 to userNum
summedValue = 0;
i = 1;
while (i<=userNum);
i=i+1
SummationWithLoop
% Write a while loop that assigns summedValue with the
% sum of all values from 1 to userNum
end

Sorry I forgot to include what I am confused about. I am a little confused about which variables I should be putting where, I know that if SummationWithLoop is 5 then the answer should be 15 (1+2+3+4+5=15).

Did you mean to create a recursive function?

You need this line:
summedValue = summedValue + i;
There is no need to call this function recursively, so omit the line
SummationWithLoop
