Here are the things I think you've got wrong or need clarification:

"Nested Functions" aren't included in Octave at all. The variable 
scoping rules in Matlab for nested functions is different than 
sub-functions. Note however that Octave had sub-functions before matlab did.

"try/catch" isn't an extension it is also in Matlab.. Matlab introduced 
in 2008a the OnCleanup function that has similar functionality to the 
unwind_protect structure, though I think the Octave way of doing it is 
cleaner.

What do you mean by "closures"?

The "GSVD" function is part of the linear-algebra package of octave-forge

The sparse SVD is part of the arpack package of octave-forge for license 
reasons...

You can write a C mex wrapper to a fortran function and so I'm not sure 
this is a real limitation.

Regards
David
