A real walk in the park, stay tuned.

BTW something *not* so simple that may arise your fancy:- as you know the Matrix function set in the Advantage can be used to work with Complex matrices, using the well-known method of "Partitioned Matrices", already described in the 15C manuals.

In fact the module comes with a CMEDIT driver program that can be used to calculate matrix inverses, and to solve systems of complex equations... however it doesn't calculate the determinants.

So here's the task: Write a routine to calculate the determinant of a Complex matrix, using the Matrix functions in the module.

Anybody going for it?
Is there any example in the Advanced HP-15C Manual perhaps?
