Did you meant to say that you simulated 'a' dipole using NEC and now you
wanted to write your own code in Matlab? I suppose you wanted to say that
the M files will eventually go for complilation into C. Answer is: Yes, it
is possible but do it if you are only going to develop your own code for
compilation.

The way I see it is that there is no point in reinventiong the wheel.

CONCEPT II can do that.

I must say that I am in no way associated with TUHH, just a user.

Read the publications relating to "Field Extension (FE)" and the
application of 'Huygen's Principle' or Kirchoff's (or Kirchhoff's?) Surface
Integral Representation KSIR. ( look up works by MJ Barth, R R McLeod & R W
Ziolkowski OR the classic R J Lubbers and K S Kunz et. al.. ..???) Or
something like that.

Hope it helps. Just another of my 2 ¢ worth .
