BigDecimal
Arithmetic and calculus with decimal numbers of arbitrary precision.
BigDecimal is a C # library that uses System.Numerics.BigInteger in its implementation, adding only a decimal place quantizer. In BigDecimal all the arithmetic operations are implemented, including, logarithms, systems resolution of linear equations, trigonometric functions, polynomial regression, hyperbolic functions, the notorious gamma function (factorial for non-integer real numbers) and more that will be implemented still. My intention is, at a minimum, to implement all the mathematical functions of the Windows calculator, and at most, if any, all the mathematical functions of Office Excel. -

ADiGator
A MATLAB Automatic Differentiation Tool
...Furthermore, these calculations are written entirely in the native MATLAB language, and thus the process may be repeated to obtain nth order derivative files. The package is particularly appealing for applications where the same derivative must be found at multiple different points, i.e. non-linear root finding/optimization, stiff ode integration, etc. -

UndoTree
The undo history visualizer for VIM
Undotree is a Vim plugin that reveals Vim's non-linear undo history as a navigable tree, letting users visualize and revisit past versions or divergent edit branches. It modifies the current buffer temporarily without saving to disk, ensuring safety during navigation. Vim's undo/redo feature is a great way to protect your work from accidental changes or data loss. Unlike other editors, where undoing and then accidentally typing something can cause you to lose your edits, Vim allows you to revert to previous states without losing any data, as long as you keep the Vim session alive. ... -

ViCuTo
A video cutting tool.
ViCuTo cuts video files and tries to limit recoding only to the boundaries of the video segments. You can use segments from different files and add other audio tracks. If the segments are encoded in different codecs ViCuTo recodes them to the codecs of the file that the longest parts of the segments come from, thus avoiding as much recoding as possible. -
