-RandIChisq : random variate from an inverse xi-squared distribution with n

degree of freedom.

-RandGamma : random variate from a gamma distribution with parameters a and

• Changed version numbers to unify all packages: Tol, Toltcl and Tolbase

• Bugs fixed: -BMTFile(Set) (​http://bugs.tol-project.org/show_bug.cgi?id=2) -CholeskiInverse (​http://bugs.tol-project.org/show_bug.cgi?id=3) -QuantileS (​http://bugs.tol-project.org/show_bug.cgi?id=4) -configure checks GSL version (​http://bugs.tol-project.org/show_bug.cgi?id=5) -Timing traces (​http://bugs.tol-project.org/show_bug.cgi?id=15) -If sentence (​http://bugs.tol-project.org/show_bug.cgi?id=18)

• Changed project structure in order to put under gnu autoconf utilities

Now support autoconf shell script "configure" to build the library

• tol library become a new Open Source project under gnu/GPL license terms.

TOL was an internal project developed from 1995 at Bayes Decisión, SA (Spain, Madrid). Is the base software used with TOLBase, another open source project. TOLBase is a user interface written in tcl/tk for programming in tol.
