CLAPACK v3.1

The Enlighten precompute uses a modified version of CLAPACK v3.1, which includes the libraries libf2c and BLAS. The source is available from http://www.netlib.org/clapack. The modifications are minor alterations to make the code compile in our build environment and remove source code we do not reference.

From netlib.org/blas/faq.html:

Are there legal restrictions on the use of BLAS reference implementation software?

The reference BLAS is a freely-available software package. It is available from netlib via anonymous ftp and the World Wide Web. Thus, it can be included in commercial software packages (and has been). We only ask that proper credit be given to the authors.
Like all software, it is copyrighted. It is not trademarked, but we do ask the following:

If you modify the source for these routines we ask that you change the name of the routine and comment the changes made to the original.

We will gladly answer any questions regarding the software. If a modification is done, however, it is the responsibility of the person who modified the routine to provide support.
