If you mean easier on the WP34S THAN on the DM42, then absolutely not. Matrix operations are very poorly implemented and difficult to use on the WP34S, and it requires careful memory management. There is no native matrix data type, and all operations require calls to functions. There is no editor for easy matrix data entry either. As far as hardware is concerned, the underlying HP 30b hardware is crippled by limited memory, so only small matrices are possible. Finally, the DM 42 has an internal flash drive for saving programs and well as a USB port for saving programs to a computer and reflashing the firmware, If you want to use matrices on something other than the DM42, you might want to try the new WP43S emulator, which is still under development.
