Do you
1) use Windows;
2) like GNU #Octave ;
3) know how to use Git;
4) enjoy trying out unsupported, bleeding-edge dev builds?

Then I invite you to try out the dev version of CVX 3.0 beta with Octave 4.0. To do so, you'll need to grab the Octave 4.0 binaries, and the "rework" branch of the CVX GitHub repo. 

Some important notes:

--- This is Windows only. I do not have binaries for Mac and Linux, and I cannot afford the time to build them myself. So I'm waiting for supported binaries for these platforms before I proceed. If you're a heavy Octave user you should consider contributing to the binary creation effort!

--- Complex variables will not work due to a known bug in Octave.

--- For some reason, there are issues with the GUI and plotting with Octave 4.0 on Windows 8.x. This is also a known bug.

--- Again, there is no support yet, and I mean that. Please don't clog up our support site or even the discussion forum with issues just yet. By all means, please feel free to report your experiences in the comments below. When I announce that the Octave support to be "beta worthy" I will invite bug reports.

While sophisticated error analysis is crucial, it shouldn't be mistaken for something that it isn't, namely a model for the physical process itself. So error analysis can't help in extending the lifetime of a battery-the sentence doesn't make sense.  It can help in estimating better, how the probability distribution of quantities, defined within a given model, can be better described. This says, however, nothing about the model itself, that must be studied separately.
