>------------------------------------------------------------------------------------------------------|
Dear list
I perform extensive numerical simulations. Until now I have used
higher-level interpreted languages like R and Ox, but for the project I am
currently working on, these are much too slow (or my implementation is too
ambitious!). Since my project is very well suited to OOP I am looking for a
C++ linear algebra package which has vectors, matrices and 3-dimensional
matrices and the ability to convert between these. Of course, I also need
LU
and QR and other standard linear algebra methods. But above all, the
package
should allow to implement efficient code.
I have been using TNT (with Array1D, Array2D and Array3D) for a while but
unfortunately this package lacks higher-level constructs, and I do not feel
sufficiently capable of implementing my own methods.
Before I make a change to another package I would like to ask you: Have you
had experiences with different C++ linear algebra packages and if so: what
are the pros and cons. Perhaps you can direct me to some information about
it.
Sincerely,
Jorn Attermann
