In v4, we were able to call
```
cheboppref('maxDegree', 4000)
```
to increase the maximum number of gridpoints that the linop solver was allowed to use. In v5, the mechanism is slightly different --…

The second last piece of the CHEBGUI puzzle, chebguiwindow.m and chebguiedit.m, which live in the trunk folder, are ready to be reviewed. The length of the files might be scary, but they mostly involv…

If you solve a nonlinear ODE and then try it again using the computed solution as the initial guess for the second attempt. you'll usually get a warming or a failure. For example, this happens in the…

If we solve `u'=u` on `[0,1]' with`u(0)=1`, the result is a nice clean chebfun of length 14 going down to a coefficient of size 1e-17. If on the other hand we solve
```
u'=u + sin(u) - sin(u), u(…

This issue presented itself in the ode/BVPSystem example. Here is a code extract from that example where the problem occurs:
```
N = chebop(-1,1);
x = chebfun('x');
N.op = @(u) [ diff(u(:,1),2) - si…

The following linear system of six unknown function arises when studying the Lorenz equation. It turns out that solving it worked fine in v4, while in v5, something is broken.
Try running the followi…

I'm using Fedora 19 i686 w/kernel 3.13.11-100.fc19.i686.PAE
I tried to build a DKMS ZFS module off a HEAD of a master branch (2c33b9127569ad62b4cfe7dd4f651ceeee3d005c at the time of writing) but got …

The chebguiExporter class, and its subclasses, chebguiExporterBVP, chebguiExporterEIG and chebguiExporterPDE are all ready to be reviewed. These classes deal with exporting problems from the chebgui f…

This is related to #861, although it was not worth holding up merging that while we decide on this. Taken from the discussion on that thread:
On development, we now get when solving an EIG problem wi…

compiler code in setup.py breaking what should be a working system - mac w/ fink. Other packages with fortran code work right out of the box with a much simpler setup.py. e.g. https://github.com/jsa…
