[Vxl-maintainers] Small patch to vnl_real_npolynomial

[Marcus B. <mbr...@cs...>]

Hi everyone,

Attached is a small patch to vnl_real_npolynomial which I've had kicking 
around for a while.  It simply adds the ability to differentiate a 
vnl_real_npolynomial or evaluate its derivatives.  It's not the most 
efficient way most likely, but it is functional.  If this is useful, 
please feel free to apply it (it would certainly make my life easier and 
make upgrading VXL much less painful for me.  It applys cleanly to 1.9.0.

As an aside, where is the tgz for 1.9.0?  I could only find a zip file.

Cheers,
Marcus
