this is my project
function[w]=check()
w=0;
q= input('Enter the name of file ','s');
switch(q)
case('dk')
if (exist('dk.wav') == 2)
disp('File is presesnt ');
w=w+1;
end
otherwise
disp('File is not presesnt ');
end

if exist(filename,'file')
fprintf('%s file exists\n',filename)
else
fprintf('%s file doesnot exist and I am creating\n',filename)
data = rand(10,1) ; % some data to write into file
