PROD on WP 34S on DM 42

[Nigel (UK)]

Just to be clear: the WP34S implementation on the DM42 hardware has exactly the same matrix capabilities as the original WP34S. I didn't add anything in this area.

To be specific, I compiled the code with MATRIX_ROWOPS and MATRIX_LU_DECOMP enabled, and SILLY_MATRIX_SUPPORT disabled.

Here's a link to the WP34S code on Sourceforge. There's a helpful file matrix.txt in the doc/ folder which goes through the available matrix commands on the WP34S. In the library/ folder there's source code for a program called MED in the file matrixedit.wp34s, which makes entering and viewing matrices less hard than it might otherwise be. The file contains documentation for the program. It can be compiled and loaded in the usual way.

If it is necessary to work with matrices on the DM42 hardware, the Free42 implementation is easier to use than the WP34S.

Hope this helps!
