28 May 2009 export_fig Exports figures nicely to a number of vector & bitmap formats. Author: Oliver Woodford

Great job!
Finally I can get publication-quality graphs in a simple way.
Thanks Oliver for making it easier than ever before.

Really nice job!

Steven,

First of all, thank you for the suggestions, I think I might have made some mistakes on the regions boundaries, since I measured all boundaries from a printed plot (on the referred articles) so nothing was very exact. I hope you could provide me with the original work from Clarke, to make the necessary corrections.

Do you have a solution of second edition? if you have that, send me please ^ ^ have a nice day.

excellent programs..........
can someone expalin to me where the waveguide(core) width and the cladding width are handled in the code for the rectangular waveguide? and what do x0, x1, x2,x3,and x4 stand for?

Overall, the logic is excellent. There are 2 suggestions: for the lower C region, the slope of the boundary should be 7/5 rather than 6/5. For the upper B-C boundary, there are two schools of though displayed in error grids being published. I think Clarke still uses a line parallel to 45deg rather than a line parallel to the +20% line. Very nice code.
