Intel® oneAPI Math Kernel Library LAPACK Examples

This document provides code examples for LAPACK (Linear Algebra PACKage) routines that solve problems in the following fields:

Linear Equations

Examples for several LAPACK routines that solve systems of linear equations.

Linear Least Squares Problems

Examples for some of the LAPACK routines that find solutions to linear least squares problems.

Symmetric Eigenproblems

Symmetric Eigenproblems has examples for LAPACK routines that compute eigenvalues and eigenvectors of real symmetric and complex Hermitian matrices.

Nonsymmetric Eigenproblems

Nonsymmetic Eigenproblems provides examples for ?geev, one of several LAPACK routines that compute eigenvalues and eigenvectors of general matrices.

Singular Value Decomposition

Examples for LAPACK routines that compute the singular value decomposition of a general rectangular matrix.

NOTE:

If you want to find a routine for a specific purpose, use the oneMKL LAPACK Function Finding Advisor. It advises you which routine to use according to parameters that you specify.
