This is just short post, to let everyone know I'm still here.
The Answer First...
An interesting MATLAB solution to the relational join problem was provided in a response to my Why MATLAB for Data Mining? posting of Nov-08-2006. I had written, "The one gap with MATLAB is that it is not very good at relational joins. Look-up tables (even large ones) for tacking on a single variable are fine, but MATLAB is not built to perform SQL-style joins.". Eric Sampson of The MathWorks (serow225) couldn't let that go, and provided a solution in his comments to that post. Thanks, Eric!
...Then The Question
The Statistics Toolbox from the MathWorks provides a discriminant analysis routine, called classify. This function performs linear, Mahalanobis and quadratic discriminant analysis- all very handy modeling algorithms. The question is: Why does classify not output the discovered discriminant coefficients?
