My purpose is to compute secondary pattern in reflector antennas and also simulate the effects of cross polarization by taking out E & H plane patterns..
In MATLAB I am supposed to do an integration involving function of r,theta,thetaprime,phi,phiprime.. Matlab just cannot do a symbolic double integration..left my comp busy for abt 1 hour for that.. in trapazoidal numeric integration,matrix dimensions NEVER agree!!
The integration involves huge cumbersome terms which are difficult to manipulate manually!
I am referring to a ieee paper by Ruze btw..
should i switch over to some other software(plz suggest!) .. or any integration algorithm in matlab? Reply ASAP..really troubled !

Hi ansish260191,
which Matlab Version You are using let me know.Matlab Version 7.6 version will support Symbolic double integration, which i have been doing.
Sloty
Most of the functions don't have an analytic integral, so I wouldn't spend to much time trying symbolic integration.
About numeric integration, check your expressions, at the end you'll find the mistake. At the end, matrix dimensions ALWAYS agree :)
