MATLAB: MATLAB Editor Code Analyzer

Question

For the following code

x=1;
save('x','x')
x=2;

the MATLAB Editor Code Analyzer warns

"The value assigned to variable 'x' might be unused." I have clearly used it; I saved it to the file 'x.mat'. This bugs me, I'd like to see a nice green box telling me my code is clean.

Answer 1

Add the %#ok pragma at the end of the line:

   x = 2;   %#ok

HTH.
