I used MATLAB coder for converting .m files to C files.
All the things are O.K. except randn() function. The problem is that auto-generated randn() function generates the same sequence of numbers all the time. So I changed it by using 'srand(time(NULL))'; and 'rand/(double)RAND_MAX';
Are there any settings for MATLAB coder to generated a different version of randn() function?
