If by "install directory" you mean the directory that MATLAB itself is installed in, then if you are using MS Windows, you would need to either Run As Administrator or else install MATLAB somewhere outside of the system Program Files directory. MS Windows blocks ordinary users from writing files into the Program Files directories.
You can specify a full path to save the file when you audiowrite it. For example,
audiowrite('C:\Users\suleyman\CS207\MATLAB\Assignmen3\OutFiles\OutputFileNameGoesHere.wav', y, 44100);
