Listing the Names of Files in a Directory

Syntax	listdir
	listdir(directory)
	listdir(directory, pattern)
See Also	dir , listdirs , exists , isdir , rmdir , findstr , find2

Description

If the argument pattern is present, listdir returns only filenames that contain strings that match the Regular Expressions specified by the character row vector pattern.

Example
If the directory c:\omwin\programs contains the files edit.oms and TEST.OMS, and you enter

O-Matrix will respond
     edit.oms
     TEST.OMS
If you enter,
    listdir([OM_INSTALL,"\function"], "^fn.*")
O-Matrix will list only the functions in the function directory that start with the characters "fn".
