MATLAB: Adding #ifdef to the generated C code

Question

I am developing code in MATLAB (m script) and need something like #ifdef to decide whether to execute a function during compilation.

Does something like #ifdef exist for m-script ?

Answer 1

You can use exist function for this process along with if else statements to achieve your goal in .m file:

Refer to exist documentation. This is a example of the same for checking if a variable is in workspace or not.

% if variable exists in the workspace
if exist('a') == 0
    disp(0)
% if variable doesn't exists in the workspace
elseif exist('a') == 1          
    disp(1)
end

The same can be checked for files as well.

Hope it helps.
