There was a problem hiding this comment.
Why are you unconditionally defining this rather than modifying configure.ac to check for it?

(Would be good to have a Scheme/libctl interface for this too, no?) Once, this PR is in good shape, it would be good to squash the commits into a single one for merging. |

I propose to include the band source into MEEP, as I originally advertised in April 2014. It gives more control to the source spectrum, e.g. to selectively excite a group of resonance modes, whereas other unwanted modes are efficiently suppressed.
More information can be found in the dedicated chapter on my website, http://fzu.cz/~dominecf/meep/index.html#bandsource
Please disregard some of the related commits, they were erroneous and I effectively reverted them later.
This feature still uses the automatic decision whether GSL is available or not (in which case the behavior changes to inaccurate, but similar sinc function). As a matter of fact, I am not able to improve this in the configure scripts at the moment. It should not be too confusing anyway, I believe.
