Since I last wrote I have made significant progress on MAVL.  The program is now producing results like that shown below.  Full AVL model generation is now possible; rudders, elevators, and control surfaces are all possible now.  The capabilities of MAVL have been expanded to create and run test cases as well as load data from files created by AVL.

In particular, MAVL can read files created by the ST and SB commands under the OPER menu as well as reading the *.eig file created from the MODE menu.  This allows the user to create models from design parameters and get immediate stability information all with out leaving matlab.  The parseEig function also classifies the eigenvalues based on their relative orders of magnitude.  This allows the user to quickly access the phugoid, short period, dutch roll, spiral mode, and roll convergence.
