Petools is a toolkit for development of scientific applications
related to processing observational data.
- Fast linear algebra routines, including one of the fastest subroutine
for inversion of a square symmetric positively determined matrix in the
upper triangular representation.
- 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.
- 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
- A set of routines for manipulation with splines; various routines for
multi-dimensional B-spline transform, etc.
- Various routines for least squares, regression computation,
error handler, interface to a low level I/O, interface to network
routines at the socket level, lists processing, date transformation, etc.
