momentproblems

Research code accompanying the thesis (tba)

This is a SageMath package with a proof-of-concept implementation of algorithms for:

• parameter recovery of certain moment problems
• generalized eigenvalues and eigenspaces of regular matrix pencils (A_0,…,A_r)

Examples and documentation

See https://momentproblems.readthedocs.io.

Installation

Requirements: A version of Sage in which LAPACK issue 475 is fixed, e.g. with OpenBLAS 0.3.14+ (included in the Sage distribution since Sage 9.5.beta6+, or can be installed manually).

First, clone the repository from GitHub and then install the package and run the tests:

git clone https://github.com/mwageringel/momentproblems.git && cd momentproblems
make SAGE=sage install test

Alternatively, to install into the Python user install directory (no root access required), run:

make SAGE=sage install-user test
