Portable Eigenmath

Portable Eigenmath is a lightweight application that can help math students or casual users who frequently work with mathematical equations, by providing them with the necessary tools for seamlessly writing complex expressions. It can be easily figured out, even by users with no experience in software programs.
Since Portable Eigenmath does not come with an installation package, it is possible to store it on an external device (like a USB flash drive), in order to run its executable file on any computer.
Thus, you can carry Portable Eigenmath in your pocket whenever you're on to go (e.g. to college for math class). Moreover, no items are left behind in the Windows Registry or on the hard drive after program removal.
The interface of the program is based on a standard window with a plain layout. So, you can write various mathematical expressions, draw a Cartesian coordinate system, calculate the float or integral value, as well as find out derivatives, among others.
Editing the script can be done at any time. In addition, you can use the undo, redo, copy and paste functions, copy the current display to the Clipboard, create a script from the command history, as well as save the script to file for further processing.
The straightforward program requires a low-to-moderate amount of system resources, is very responsive to keyboard commands and mouse events, and includes a Help menu for the functions it supports (e.g. complex, polynomial, linear, circular, exponential). We have not experienced any issues during our evaluation; Portable Eigenmath did not freeze, crash or display error dialogs. Unfortunately, no recent updates have been made.
