error in a Matlab toolbox. Problem with" cellfun".

[Philipp Leser]

Hey,

I try to play around with the Matlog  (http://www.ise.ncsu.edu/kay/matlog/)toolbox and run it on Octave. It’s quite interesting since I can run Matlog on MATLAB at the university and compare it to Octave. On Matlab the Matlog toolbox runs quite smooth, but on Octave I get some error messages. To me it is an educating experience on the few incompatibilities of the two tools.

 

 Here is one error I really have trouble understanding. Would be happy about any hints or help.

 

I run the function “vrpsavings”.  The function itself calls a function called LocTC in an “try and catch” construction:

 

 

“try  % Use for error checking and to store input arguments

   locTC([],C,cap,twin,locfeas);

catch

   errstr = lasterr;

   idx = find(double(errstr) == 10);

   error(errstr(idx(1)+1:end))

end “;

 

where  C is a NxN matrix, cap a cell object and twin locfeas are a [] double.

 

 

In  the line “ locTC([],C,cap,twin,locfeas)” I get the error message.

 

“error: cellfun: second argument must be a cell array

error: evaluating argument list element number 1

error: evaluating argument list element number 1

error: called from:

error:   C:\Octave\3.2.2_gcc-4.3.0\bin\matlog\locTC.m at line 180, column 1

error:   C:\Octave\3.2.2_gcc-4.3.0\bin\matlog\vrpsavings_test.m at line 54, column 1

“

 

In “locTC” line 180 to 186

 

 

 

“

if isfirstcall & ~isempty(loc) & (~(isreal(loc) | iscell(loc)) | ...

      (~iscell(loc) & (min(size(loc)) ~= 1 | ...

      any(loc(:) < 1 | loc(:) > n))) | ...

      (iscell(loc) & (any(cellfun('prodofsize',loc) ~= ...

      cellfun('length',loc)) | any([loc{:}] < 1 | [loc{:}] > n))))

   error('"loc" not a valid loc seq.')

end

“

 

 

When I run the “vrpsavings” file  in the Matlab debugger, the “locTC([],C,cap,twin,locfeas)” returns “inf”, but no error.

Why? I don’t get it.

 

Thanks in advance
