leasqr question (again)

[seektime]

Hi,

I'd like to run leasqr.m in its simplest form, ie without any options (just
bare bones) but I'm getting the following error message (variables pasted
below if you want to test it on your system):

octave:3> [f,p]=leasqr(V,I,pin,F)
error: Invalid call to options.  Correct usage is:

 -- Function File: OPT = options ("KEY1", VALUE1, "KEY2", VALUE2, ...)

error: called from:
error:  
C:\octave\Octave3.6.1_gcc4.6.2\share\octave\3.6.1\m\help\print_usage.m at
line 87, column 5
error:  
C:\octave\Octave3.6.1_gcc4.6.2\share\octave\packages\control-2.3.52\options.m
at line 68, column 5
error: evaluating argument list element number 1
error:  
C:\octave\Octave3.6.1_gcc4.6.2\share\octave\packages\optim-1.2.0\leasqr.m at
line 574, column 5

Code and variables are:


V=[
 -159.88
 -149.27
  -139.1
 -129.08
 -118.97
  -113.9
 -108.86
 -103.82
 -98.762
 -93.748
 -88.717
 -83.669
 -78.658
 -68.557
 -58.494
 -48.459];
 
 I=[
           1
  1.0079
 0.97652
 0.87318
 0.81173
 0.72704
 0.66648
 0.57694
 0.39872
 0.29661
 0.18571
0.094664
0.047699
0.035285
0.021977
0.017704];

pin=([-100 -10]);
F = @(V,p) 1 ./ (1 + exp((p(1) - V) / p(2)));

Besides that fact that it doesn't return the parameters I'm wondering about
the message since I'm not passing any options? Any hints, explanations or
suggestions would be highly appreciated.

Michael
