: I would like to write (or buy) a program in EXCEL VBA to solve a portfolio problem (quadratic optimization with linear constraints). N will be less than 20. Where could I find an algorithm? Or code.
: BTW Excel has built-in matrix inversion and multiplication functions.
: I have an undergraduate degree in math (about 15 years ago), so I'm rusty.
Have you tried Frontline (who make the standard Excel Solver) ?
