Packaged Octave in CAE 2011

Thank you for all your efforts putting these packages together. I am new to FEA and your packages have been very helpful to get a system working with little effort on my part. It seems anytime I have looked at LINUX, I spend more time trying to get the software all working that I do actually using the software.


Now that 2011 is out and only available as 64-bit, I wonder if you would consider using a 64-bit Octave. It would also be nice to include some of the common packages.

Thanks for any consideration.

Thank you for your response.

If you open a terminal and type:

octave --eval 'b=17000; x=rand(b,b); size(x)'


You will see the following message:

error: memory exhausted or requested size too large for range of Octave's index type -- eval failed

With 2011 now only supporting the 64-bit platforms, it seems to make sense to take full advantage of this with the tools.

With the 64-bit CAELinux 2010, Octave 3.2.4 built for 64-bit and running under the original QtOctave I have tested the following packages:

specfun-1.0.9
struct-1.0.9
miscellaneous-1.0.10
optim-1.0.15
signal-1.0.11
control-1.0.10


There appears to many changes to the FAE software included with 2011. It's a very nice package. I have been trying to get the new Octave running under it with the 64-bit switch, but not being a software programmer I have had no luck.

Again, thanks for all your efforts with the CAE project.<br /><br />Post edited by: joe smith, at: 2011/11/16 18:52

They may be waiting on the Octave group to make it a standard rather than keeping it experimental. Again, not being any sort of software developer and looking at the problem as a user of the tools, it appears one problem with Octave is coming up with standards that would work for multiple computers. From what I have read, much of the lower level software that Octave uses is not free (if you are looking for performance). Maybe as 64-bit PCs become the norm, this will be less of a problem.

Finding what versions of support files work with which version of the main tools and are built with what version of compilers is a nightmare for someone like me. Currently I am happy to see anything just work reguardless of perfromance. Haveing a stable snapshot of compatible tools like CAE provides is really a time saver in that users don't have to spend countless hours trying to get the tools running. You have done a great job!

I attached a screen shot of my system running CAE 2011 in a VirtualBox under Windows 7, with an older version of Octave with 64-bit indexing enabled.
