Its showing Not enough input arguments. Error in sum2 (line 2) m(:,3) = m(:,1) + m(:,2);

Hi, I'm very new to MATLAB and I am having some trouble. Lots of people have had the same problem but nobody seems to be able to explain or solve it in plain English. Could somebody please explain what this error is and how to fix it?

My function is :

function sum2(m)
m(:,3) = m(:,1) + m(:,2);
fprintf('\n Summation of Columns\n');
m(:,3)'
end

An i am getting error like Not enough input arguments.

Error in sum2 (line 2)

m(:,3) = m(:,1) + m(:,2);

please help me !!

its urgent.

do you want sum only a single column or all column ?

I think you are running the code/ function straight away using hit button or F5 key. You are not supposed to do that. You need to be in the directory where the function is saved and provide its input and then call the function.

m = rand(5,2) ;  % some ddummy data for demo 
sum2(m)   % now call the function
