08 Apr 2012 fulldiff.m Symbolically computes full derivative wrt time using chain rule and time variables. Author: Timothy Jorris

I am having a problem running this code on Matlab 2010a.
I even tried the example in the mfile
clc
clear all
close all
syms x y dx d2y

f = x*y*(dx^2)*(d2y)
fulldiff(f) % (assumes x only) produces
% 3
% y dx d2y + 2 x y dx d2y d2x
% whereas
fulldiff(f,{x, y}) % produces
% 3 2 2
% y dx d2y + 2 x y dx d2y d2x + x dx d2y dy + x y dx d3y
But I keep getting the following error:
??? Error using ==> strfind
Inputs must be character arrays.

Error in ==> fulldiff>findhigher at 153
cid=strfind(allvar,',');

Error in ==> fulldiff at 120
dvars=findhigher(fun,vars,dvars);

Please advise
