LyME is a port of LME ("Lightweight Math Engine", the heart of Sysquake) to Palm OS handheld devices. It implements about 360 native commands, functions and operators, mostly compatible with Matlab. Libraries add about 70 other functions in domains such as statistics, geometry, automatic control, etc.
LyME 3.0 is based on LME 5.0.
LyME requires Palm OS 3.1 or higher and at least 1.5 MBytes of free memory. Palm OS 3.5 or higher is preferred; Palm OS 5 offers optimal performance and functionality.
Files to be installed on your Palm device are located in the "install" folder.
Install all the files in the "install" folder to your device using your backup application, in two steps: first LyME.prc and MathLib.prc (only LyME.prc if you have a Handspring handheld), then all .pdb files (crashes have sometimes been observed if all files are installed in one step). MathLib.prc must be stored in main memory, not in an expansion module.
Install at least LyME.prc.
Unless it has already been installed for another application, install also MathLib.prc in main memory (not in an expansion module). Handspring devices (and maybe other Palm OS devices) should not need it, because MathLib is included in the device ROM. There is no harm in trying LyME without MathLib first, and installing MathLib later if this does not work.
To install additional functions provided as libraries, install one or more libraries:
The first time you run LyME, these libraries will be imported to LyME main database. If you upgrade them (or if you add any library which already exists on the handheld), LyME will ask you whether you want to discard the previous version.
Folder "lib" contains the libraries as text files, which you can view and edit in any text editor. Use the M-file in folder "db" to update the PDB files or add your own libraries with Matlab or Sysquake.
If you've installed demo.pdb:

While it's based on the same computation engine and language, Sysquake has a completely different graphical system, whose goal is nearly instantaneous interactivity with the mouse. This interactivity opens a new dimension (effect of parametric variations, relationships between different figures, etc.) and permits the user to get an intuitive understanding of his/her problems and to solve them more efficiently. Sysquake also has file support, extensions, large high-quality numerical libraries, a user interface which supports many more options, print support, and many other features.
LyME runs on much slower hardware (typically 1000 times slower); it's useful for small-to-medium-size problems and is located somewhere between high-end scientific calculators and desktop numeric software such as Matlab, with which it's largely compatible.

While LyME runs only on Palm OS devices, Calerga also develops products for Pocket PC. Currently, an LME-based application is proposed as a technology preview.
