How to create a directory using mobile number of a particular username..

I need how to create a directory with the name of user's mobile number. suppose the user mobile number is 8511356595. the same number must be a foldername of that user to differentiate the next user. when I'm getting this mobile number from the database it is displaying like this [8.5114e+09]. When I create a folder using mkdir command, asking argument must be a string... Please help me.....

Well, obviously, you need to convert the number to a string, which can be done with any of the many functions that do it:

foldername = sprintf('%d', mobilenumber);

or

foldername = num2str(mobilenumber);

or

foldername = compose('%d', mobilenumber);

Also, read about the format command which changes how the numbers are displayed in the command window only, not how they're stored.

I use the above code in my program, I'm getting the error..

Undefined function 'abs' for input arguments of type 'cell'.
Error in num2str (line 65)
      xmax = double(max(abs(widthCopy(:))));
Error in Image_mag1/callback (line 50)
fname = num2str(fname) ;
