hello, following the success of my first talk about Octave at Prague university, I'm giving one more speech tomorrow. This time, I've been directly asked by a student for more detailed feature overview & comparison with Matlab. Please find the draft presentation attached. Features are presented as keywords, with colors used to distinguish status (common, Octave-only, added in 3.2, improved in 3.2, missing). Not suprisingly I know best about the features I've been involved with, but I'd like to cover the rest as well, especially plotting. Feel free to suggest additions & modifications. I may yet add some myself. cheers
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-forgeThe 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.
