Hyper Matrix 1.0   (details) 39/40 ENG   2 KB / 4 KB
Lets students work with matrix calculations as quickly as possible. When it starts, it displays a list of matrix calculations you can perform (add, subtract, inverse, etc.). After choosing one, the program asks you for two matrices, namely M1 and M2. Once that's done the answer is automatically displayed and stored in M1. I've even programmed it to detect when certain calculations aren't possible. While this may sound like a lengthy process, it does take place a lot faster.

Transfer Aplet   (details) 39/40 ENG   1 KB / 1 KB
ScreenshotYou may be aware that one of the problems with the HP39G and HP40G is that whole rows or columns of keys will occasionally stop working. If you can still access the APLET view and the screen keys then this aplet will transfer you into the Program or Note views so that you can use SAVE/RECV to save them to a PC (assuming that you have a cable) before getting your calculator replaced.
By Colin Croft. 2017-07-24

Unlib   (details) 39/40 ENG   36 KB / 1 KB
This is a library that kills other libraries! Libraries are small attachments of machine code that come with some aplets. You can see if you have any on your machine by pressing SHIFT MEMORY and looking under the Library heading. Most of them automatically delete with their parent aplet but some don't and there's no way to delete them then. This library will do it. Just note the decimal number next to the library in the MEMORY view and then type UNLIB(number) in the HOME view. Providing that it's not in use then it will be gone. You can't delete the UnLib library itself but since it's only 189 bytes in size that hardly matters.
