Safely disconnect the calculator and wait for it to finish 'updating the Main Memory'. Copy the 'eigensup.txt' file to that folder you created.On the 'pendisk', create the folder (must be all-caps).If you also have a 'eigensup.txt' file - this is the 'startup script' we'll explain in detail, later - you can copy it too, but to a different folder: When it's finished, your Prizm will appear on your computer as if it were a pendisk.Ĭopy 'eigenmath.g3a' to the root folder of the 'pendisk' (i.e., out of any folders but inside the pendisk if necessary, overwrite the existing file). Wait for the USB connection to be established. On the calculator, press when a pop-up appears on the screen. To install, connect the Prizm calculator to the computer with a miniUSBUSB cable. System requirementsĬasio fx-CG 10 or fx-CG 20, running any OS version (01.03 and up is recommended) ģ00 KiB of storage memory available (for the add-in g3a and data files for session persistence) Ģ4 bytes of main memory available (only necessary if session persistence is disabled, to store the preference) *OSEigenmath translation not provided, although some expressions may run as-is. UI customizability: define commands to execute when certain keys are pressed. Persistent custom functions supported: a certain file will be executed as script whenever Eigenmath's 'clear' command is issued, just put your custom functions and constants there. Pressing will insert sin( in the command line, pressing, will insert arccos(, pressing will insert log( (since Eigenmath's log is the natural logarithm), and so on Most keys from the keyboard mapped to Eigenmath commands. Paste commands from system clipboard and copy commands and results into the system clipboard* Session persistence (optional): exit Eigenmath, then open it again, and everything will be there as before leaving, including console scrollback, command history and user symbols (custom variables and functions) ĮActivity strip support a script can be included in the strip, to be run when it is opened Output pretty-printing: while not as nice as the one done by the OS on built-in math screens, this still is much better than what you get with most Eigenmath ports:īracket color-matching on command input (like the OS does) Ģ00 lines of console scrollback and 40 command history entries In addition to this, there are also some features exclusive to this port, some of which only make sense to include with the Prizm platform: Script execution and creation ('recording') įunction catalog (with help for each function). Graph plotting (zoom in and out, move left/right/up/down as with the OS) Some features from the graphical versions and ports of Eigenmath are also available, with different UI (adequate to the platform), including: This means certain commands are going to take longer to execute, and certain ones won't complete due to lack of memory (640K ought to be enough for anybody, as if it's 1981 again).

FeaturesĪll of the functionality of the command-line version of Eigenmath is available on this port, with limitations consistent with the technical limits of the Casio Prizm platform. This is a port of the Eigenmath math engine to the Casio Prizm in the form of an add-in, providing numerous math functions not available in the OS, including symbolic computation.
