MATLAB Function Reference

fclose

Close one or more open files

Syntax

• status = fclose(fid)
  status = fclose('all')
  

Description

status = fclose(fid) closes the specified file if it is open, returning 0 if successful and -1 if unsuccessful. Argument fid is a file identifier associated with an open file. (See fopen for a complete description of fid).

If fid does not represent an open file, or if it is equal to 0, 1, or 2, then fclose throws an error.

status = fclose('all') closes all open files (except standard input, output, and error), returning 0 if successful and -1 if unsuccessful.
