EXIST	Check if variables or functions exist.
	EXIST('A') returns:
	  0 if A does not exist
	  1 if A is a variable in the workspace
	  2 if A is an M-file on MATLAB's search path
	  3 if A is a MEX-file on MATLAB's search path
	  4 if A is a compiled SIMULINK function
	  5 if A is a built-in MATLAB function

	Note: EXIST('A') also returns 2 if a file named
	just 'A' is on MATLAB's search path.
