fsolve and parameter dependent functions

[Kenneth Duncan Strouts]

Say I have a set up like this;

function y = f(x)
  ... stuff ...
endfunction

Then I can call fsolve("f",init) with init specifying initial  
conditions.  And it works really nicely.

However what if the function is to include a parameter,

function y = f(x,p)
  ... stuff ...
endfunction

I want to specify p *when I call* fsolve.  Is this possible?  One  
could conceivably pass p through initial conditions and treat it as a  
variable, however I don't want to do this!  Is there a cleaner way to  
do it?

Thanks!
