22 Dec 2010	matlabVMEC MATLAB interface to aid in plotting of VMEC output. Author: Samuel Lazerson	An issue has been identified for tokamaks (ntor=0). The code uses ntor5 gridpoints in zeta to attempt to resolve the highest mode number. If ntor=0 then this causes problems. The fix is simple and will be included in the next release (sometime in the first quarter of 2011). If you have issues please email me and I'll send you an updated .m file. Thanks to Peter Kavran for brining the problem to my attention.
30 Aug 2010	read_netcdf Reads a netCDF file and returns the contents as elements of a structure. Author: Samuel Lazerson	Users should check the format of arrays read by this routine. It appears that the resulting MATLAB arrays may be stored in reverse order from which they were stored. This is most likely due to the use of the copyToNDJavaArray call.
30 Aug 2010	read_netcdf Reads a netCDF file and returns the contents as elements of a structure. Author: Samuel Lazerson	A new version has been uploaded (v0.95) which uses Java to process the netCDF file. This seems to resolve any data inconsistency. If you experience any issues reading a netCDF file using this routine I encourage you to contact me and provide an example netCDF file so I can address whatever issue exists.
30 Aug 2010	read_netcdf Reads a netCDF file and returns the contents as elements of a structure. Author: Samuel Lazerson	I just noticed issues regarding some netCDF files. I believe the issue is the MATLAB routines which I use to actually read the netCDF file. More specifically trying to read large arrays of type double. I've had better luck just using the Java calls so next week I'll post up a v1.5 of this function which uses the Java calls rather than the MATLAB (C routines). Please post up any issues you run into.
