MATLAB: For loops: Odds sum

Write a for loop that assigns summedValue with the sum of allodd values from 1 to userNum. Assume userNume is always greaterthan or equal to 1.

Ex: If userNum is 5, then summedValue is 9 (i.e. 1 + 3 + 5 =9).

here is what I am given:

function summedValue = OddsSum(userNum)
summedValue = 0;

% Write a for loop that assigns summedValue withthe
% sum of all odd values from 1 to userNum

end
