lsode: passing function body as a string is obsolete. Please use anonym,ous functions.

[Richard O. Legendi]

Hi all,

I haven't used Octave so far, but I find it pretty useful, thanks for 
this great application!

I'm having some minor problems using it. I'm trying to connect it with 
Java with JavaOctave (which is working perfectly), but there's an 
example on the following page:

        http://kenai.com/projects/javaoctave/pages/Home

When I tried to run it in Octave it generates a warning:

octave:2> result = lsode("sqrt(1-t**2)", 0, [0 1])(2);
warning: lsode: passing function body as a string is obsolete. Please 
use anonymous functions.
warning: lsode: ignoring imaginary part returned from user-supplied function
octave:3> result
result =  0.78540

I wanted to eliminate it, but I keep getting a very different result:

octave:4> result = lsode(@(t) sqrt(1-t**2), 0, [0 1])(2);
octave:5> result
result =  0.84147
octave:6>

Any suggestions how to remove that warning? Any help would be greatly 
appreciated!

Best regards,
Richard
