Function Call From Inside A Command File

[Damian Harty]

O learned Denizens,

 

I’m having a spot of bother.

 

I have an Octave function file which uses nelder_mead_min to do some stuff and it works just fine…when I run it in Octave “standalone”.

 

But it fails when I run it from a command (BAT) file.

 

To define terms:

 

“Standalone” – by double clicking the Octave 3.6.4_gcc4.6.2 on my Windows 7 64 bit machine. The properties of the icon are: C:\Octave\Octave3.6.4_gcc4.6.2_20130408\Octave3.6.4_gcc4.6.2\bin\octave.exe -i --line-editing

 

I run the file which contains the nelder_mead_min call and it works just dandy.

 

“from a command file” – I have the following line:

call C:\Octave\Octave3.6.4_gcc4.6.2_20130408\Octave3.6.4_gcc4.6.2\bin\octave.exe -qf weave_damping.m

 

All the commands up to nelder_mead_min work fine but then I get :

error: 'nelder_mead_min' undefined near line 79 column 20

error: called from:

error:   C:\010-Automated_Weave_Damping_Metric\weave_damping.m at line 79, column 18

Done.

 

If I just run octave on the command line (same command as above with no arguments), I get an octave prompt and when typing “help nelder_mead_min” I can see that:

'nelder_mead_min' is a function from the file C:\Octave\Octave3.6.4_gcc4.6.2_20130408\Octave3.6.4_gcc4.6.2\share\octave\packages\optim-1.2.2\nelder_mead_min.m

 

 

I would just use that path directly but because I’m not sure how it would fit into my function call:

[par0, v0, nev] = nelder_mead_min (@(par) DampedOscillationFunction(par,X_This,Y_DASH_This,targetcurve),initial_guesses);

 

I’m presuming I somehow need to add something to the command file (or perhaps some kind of otaverc file?) to get it to add the path to the function, but I know not what or whether that is the right way of going about things.

 

Suggestions gratefully received, including RTFM if you can give me a hint where to read.

 

Regards,

 

Damian
