02 Jul 2011 
A couple of minor changes to the interp_geom.m file. Some subarray and reflector modelling examples added 
09 Sep 2013 
All filenames have been changed to lower case, hopefully improving compatibility with later versions of Matlab. There is also additional information on phased array and phase shifter design, as I get many questions on this. 
29 Oct 2013 
I found a problem with statistical variation functions plot_theta_statvar and plot_phi_statvar. The random errors were not being applied to all array elements. Apologies for any confusion / inconvenience caused. 
10 Mar 2015 
In this update, nearfield analysis and calculation of absolute values for gain and radiated field quantities have been added. See the : ‘Change Log’, ‘FAQ’ and ‘What’s new in ArrayCalc v2.5’ in the documentation folder for details. 
11 Mar 2015 
Just noticed there were lots of extra required products listed, I didn't add them, still just Matlab itself.
