Is there a way to solve a system of equations on the DM42 with complex coefficients? i.e. A*X=B; where A contains complex numbers of the form a+jb.
Any help would be appreciated.
Thanks,
Greg

Perhaps I'm misunderstanding but would it be the same as with a regular matrix but just using a complex matrix?
Create the empty matrix, press Enter to duplicate it, then press COMPLEX to create a complex matrix. Then fill in the matrix with the complex numbers?
Create correctly sized matrix A, duplicate it, turn it complex, and then edit it to fill in the complex numbers.
Create correctly sized matrix B, duplicate it, turn it complex, and then edit it to fill in the complex numbers.
Inverse A, then multiply it by B (A^-1 in y-register, B in X).

Thank you for this information. This is exactly what I needed to know.

With B in Y and A in X, divide. This is both faster and more accurate than inverting A, then multiplying by B.

There's a very nice manual available for the HP-42S which is the mother of Free42 which is the mathematical part of the SW running on the DM42. Just search the web a bit.
WP43 SN00000, 34S, and 31S for obvious reasons; HP-35, 45, ..., 35S, 15CE, DM16L S/N# 00093, DM42β SN:00041

Said manual is even linked to on the SwissMicros website.
