Description
Matlab function to list subclasses and dependencies
Syntax
getSublasses(ROOTCLASS, [ROOTPATH])

Lists all subclasses of ROOTCLASS and their node dependency. ROOTCLASS can be a string with the name of the class, an object or a meta.class().

It looks for subclasses in the ROOTPATH folder and in all its subfolders (at any depth). If ROOTPATH is not specified, it is set to the folder where ROOTCLASS is located. ROOTCLASS can also be a negative integer indicating how many folders above that of ROOTCLASS to begin the search.
Output

Produces a table with names, from and to nodes, i.e. the current and the node of the direct subclass.

If the getSubclasses() is called without an output, it will plot a graph() with the dependencies (requires version R2015b).

Example
which sde
C:\Program Files\MATLAB\R2016a\toolbox\finance\finsupport\@sde\sde.m % sde constructor

getSubclasses('sde','C:\Program Files\MATLAB\R2016a\toolbox\finance\finsupport\');
