Help text

WHICH	Locate functions and files.
	WHICH FCN displays the full pathname of the specified function.
	The function can be an M-file, MEX-file, SIMULINK Graphical function,
	or built in.  Built in functions and SIMULINK functions display a 
	message indicating that they are built in or part of SIMULINK.

	For example, "which inv" reveals that INV is a built in function and
	"which pinv" indicates that PINV is in directory toolbox/matlab/linalg.
	On the other hand "which inverse" probably says "inverse cannot be
	found" because there is no file "inverse.m" on the default MATLABPATH.
	Contrast this with "lookfor inverse" which takes longer to run, but
	which finds several matches to the keyword "inverse" in its search
	through all the HELP entries.  (If "inverse.m" does exist in the 
	current directory, or in some private directory that has been added
	to MATLABPATH, "which inverse" would find it.)

	See also DIR, HELP, WHO, WHAT, EXIST, LOOKFOR.
