Problem with fminunc.m

Hi

 

I'm using a MatLab library to help me with computer vision (http://www.mathworks.com/matlabcentral/fileexchange/loadFile.do?objectId=4576&objectType=file). With version 3.0.5, I didn't have any problems with the torr_test_calib method whereas with 3.2.0 it gives me the following result (with some unary operators not implemented).

 

> torr_test_calib_sc

focal_length =  2.4450

error before non-linear minimization

ans =  14.823

warning: list objects are deprecated; use cell arrays instead

warning: struct_contains is obsolete and will be removed from a future version of Octave; please use isfield instead

error: unary operator `'' not implemented for `list' operands

octave-3.2.0.exe:2:d:\projects\CActusCommerce\Video\MatLab\Torr

 

Can someone please help regarding this?

 

Thanks

 

Phil

With the core fminunc (no package), it seems to work for me if I alter
the fminunc call int torr_nonlinG.m to the modern-style call:
g = fminunc(@(g) torr_errg_sse (g,nx1,ny1,nx2,ny2,m3,C), g_init);

Note that neither "Display" nor "Diagnostics" options are currently recognized.

best,

Bug in optim-1.0.6

by Philippe Lavoie :: Rate this Message:

You are correct,

I modified the line as you stated and then I did

>pkg unload optim

I re-ran torr_test_calib_sc and it works. So this should be filed as a bug in the optim-1.0.6 package then? i.e. fminunc works in Core but not in Optim.
