fsolve inside fsolve

[Brian Bucher]

Greetings,

I'm attempting to use fsolve to solve for something inside a function 
that was itself called with fsolve.  I'm getting

error: fsolve: invalid recursive call


The playing field:
OS: Mac OS X 10.3.9
Octave version: 2.1.53-1 installed via Fink (FinkCommander)


octave:11> call_bname2
yguess = 0.50000
xguess = 0.50000
error: fsolve: invalid recursive call
error: called from `bname2' in file `/Users/blah/octave_playing/bname2.m'
error: fsolve: evaluation of user-supplied function failed
error: near line 5 of file `/Users/blah/octave_playing/call_bname2.m'
octave:11>



--- file call_bname2.m ---
yguess = 0.5
[y, binfo] = fsolve('bname2', yguess)


--- file bname2.m ---
function g = bname2(yin)
        xguess = 0.5
        [x, info] = fsolve('bname', xguess)
        g = 0.7 - yin
endfunction


--- file bname.m ---
function f = bname(xin)
        f = 0.8 - xin
endfunction



Is there any way to do this?

Thank you,
Brian
