Thank you. It's creating the new file. But it is not able to read this file when I gave its path to another function. Is there any command for that?

There are lots of commands for that. Can you be more specific when you say the other function can't read the file? Do you get an error? Do you get unexpected results? What code have you tried so far?

All MATLAB functions that read/write to data files accept absolute/relative filenames, so you just need to add a relative/absolute path to the filename. You can easily create the complete filename using fullfile.
D = 'C:\somedir\subdir';
N = 'myfile.txt';
fid = fopen(fullfile(D,N),'wt');
...
fclose(fid)

the fullfile() function is useful when you write several files inside a for loop ,for instance. THANK YOU Stephan
