Petools is a personal toolkit of Leonid Petrov.

It includes

1. Fast linear algebra routines, including one of the fastest subroutine for inversion of a square symmetric positively determined matrix in the upper triangular representation.
2. Graphic library DiaGI (Dialog Graphic Interface) which makes a plot of one-dimensional function(s) from one call and allows a user to adjust parameters of the plot interactively.
3. Routine MatView which displays a portion of a big matrix on the screen and allows a user to change the boundaries of the displayed area interactively.
4. A set of routines for manipulation with splines.
5. Various routines for least squares, regression computation, error handler, interface to a low level I/O, date transformation etc.
