Global Flag

Dear All I am using global flag in my code, and there is two parts of equations to be run. e.g when flag =0 , there is set of equations (let's call it No.1 )should be run, while when flag = 1, other set of equations (set No.2)should be run.However, when I am running the code with using flag =0 or = 1, for both case only set No.2 (of equations) is running. Any suggestion please ?

Regards

Are you sure you're using == and not =?

if flag = 1  % Incorrect.
if flag == 1 % Correct.

Or better yet, if there are only those two values, make flag a logical

if flag

or

if ~flag

Dear

Thanks for reply

Sorry there was a typo in my previous message . I meant flag == 1

I have another value of flag which is running a test for my equations (flag==2).

could I use (in this case for there values of Flag), (~flag) command?

you can use a switch statement

switch flag

case 0

blah

case 1

blah

case 2

blah

otherwise

blah

end

So is it solved or not? If you're checking each value of flag (1,2,3,etc) with an if statement and they're integers and you're using double equals, then there is no reason it should always go into the same if block regardless of what the value of flag is.
