It fixes the problem for me, so I'm closing this report.

Maybe an additional hint: When I run

d(2) = cfg_dep;

where d does not exist before, I get a vector of cfg_dep objects. However, only d(2) gets properly initialised. The fields of d(1) are set to something, but not to their initial values.

I have not yet found why the index out of bounds error is happening, but I discovered a segfault if I do

matlabbatch{1}.spm.spatial.realign.estimate.eoptions.weight = '';
matlabbatch{2}.spm.spatial.realign.write.data(1) = cfg_dep;

Jaroslav, do you see why this error and crash are happening?

In the context of SPM, I try to create an array of custom objects. However, the following code fails:

matlabbatch{1}.spm.spatial.realign.estimate.eoptions.weight = '';
matlabbatch{2}.spm.spatial.realign.write.data(1) = cfg_dep;
error: subsref: A(I): index out of bounds; value 1 out of bound 0
error: called from:
error:   /home/volkmar/octave/@cfg_dep/subsref.m at line 29, column 5

Similar code works:

matlabbatch{1}.spm.spatial.realign.estimate.eoptions.weight = '';
matlabbatch{2}.spm.spatial.realign.write.data = cfg_dep;

Unfortunately, I can't simply use the second version of the code, since the first version of code exists in many scripts that SPM users created on their own.
