I want to calculate all the combinations for a X number of variables and I am doing this code:
m=6;%number of variables
TC=0;
for n=1:m,
C=factorial(m)/((factorial(n)*factorial(m-n));
TC=TC+C; %total number of combinations
end
TC
but I have the following error message from MATLAB:
Unbalanced or unexpected parenthesis or bracket.
Does anybody know which would be the right code to compute the total number of combinations, or where is the error in my code?

C=factorial(m)/((factorial(n)*factorial(m-n));
You are opening two parentheses, but closing only one in the denominator

The error is due to a missing bracket at the end of this line:
C=factorial(m)/((factorial(n)*factorial(m-n));
Add a bracket and it works.
C=factorial(m)/((factorial(n)*factorial(m-n)));
