I recently revised BLACKART to make the coefficient matrix data structure and associated vector data structures more compact. See the related Blackart Interpolation article on this site. As a result of the correction the new version converges much more quickly than the previous version. I corrected an error in the initial estimate vector computed by BLACKART. See the related Blackart Interpolation article. Input files of size 1201 by 1201 elevation nodes are now no problem. This version also has a compiler optimization that allows the code to run much faster than the console version. This version fixed a couple of bugs discovered on deployment, like turning off the RTL and RT Package DLL switches and fixing the window sizing attributes. However, I think it is worth releasing as it is a lot better than the previous console application, having a proper GUI and some input error checking. It is a beta version that does not include many necessary features such as exact output file alignment and graphics capability. This is the windows version of BLACKART replacing the very short-lived v1.03.
