Is there a better option for first order ODE solving/plotting in Matlab than dfield8? It gives me problems every time I attempt to enter differential equations. My latest issue is as follows:
Reference to non-existent field 'axes'.
Error in dfield8 (line 813)
aud = get(dud.axes,'UserData');
Error while evaluating UIControl Callback
Any help or better options would be much appreciated.

It would be a great service, yes -- but performing the service doesn't pay any bills.

Errors also arise due to the use of:
if notice
if dud.notice
These are corrected by:
if ~isEmpty(notice)
if ~isEmpty(dud.notice)

Hello, very nice answer, but in Matlab R2015a (Windows7): Undefined function '~isEmpty'!
'~isempty' works for me.

you will find the both editions in this link (one for Matlab 2014 and before, the other is for Matlab 2015 and later):
Update: the file of pplane8.m which found in this link works for Matlab 2015 and later :)

go through and replace every occurrence of 'numb' (the quoted string exactly like that) with 'numbertitle'. . Also replace one 'number' (the quotes string exactly like that) with 'numbertitle'
