Hallo, you could look at http://www.adapower.com/schroer/lib-src.zip . You will find some generic packages (math.generics.arrays.matrix_operations and others) containing matrix / vector algebra. I have also numerical algorithms (a subset of LINACK for linear algebra, linear equation sovlvers, etc. and a subset of EISPACK for eigenvalue/eigenvector problems using HQREV / HQREW). This software is in Ada83 and I intend to adapt it to Ada95 (give it a hierarchical package structure, use new attributes and packages from the Predefined Language Environment etc.) before publishing it. I think I cannot do this job before the end of the year, so contact me if you want the Ada83 packages. -- Joachim Schr�er http://www.adapower.com/schroer "Russ" <18k11tm001@sneakemail.com> schrieb im Newsbeitrag news:bebbba07.0107121059.4696bbb6@posting.google.com... > I am new to Ada (I just compiled "Hello, world" yesterday).
