Package de.jtem.jtao Description

This package makes a part of the functionality of the numeric library TAO accessible for Java programs. As the TAO project it depends on PETSc, which is accessed via the jPETSc project (also on jtem). Both utilize the JNI to achieve that.

What it can

At the moment it is possible

• to use TAO to solve unconstrained optimization problems, using PETSc for the linear algebra

How to use

See the corresponding section of the jPETSc documentation.

Examples

A small jTAO example

This simple example uses jPETScTao to find and calculate the minimum of:
f: R->R , x|-> x^2
