can't find documentation of lapack functions

Tomasoni — Thu, 07 Jul 2022 12:43:04 GMT

Hello all, I'm trying to migrate a software that is using mkl 2019.2 to the latest version.

I'm looking for the functions I was using but I hardly can find the documentation.

For instance through search engines I found this page of a function I am using

https://www.intel.com/content/www/us/en/develop/documentation/onemkl-lapack-examples/top/least-squares-and-eigenvalue-problems/symmetric-eigenproblems/syevr-function/dsyevr-example.html

in the page I read

For a detailed description and reference information on this function, please visit:

?syevr function in Intel® oneAPI Math Kernel Library Developer Reference - C

But if I click on the aftermentioned link I will get redirected to a generic page.

Can you please point me to the documentation, as well as a list of changes I should apply to make my code compatibile with mkl 2022?

Thank you

Danilo

For use with C, the link is https://www.intel.com/content/www/us/en/develop/documentation/onemkl-developer-reference-c/top.html .

For use with Fortran, the link is https://www.intel.com/content/www/us/en/develop/documentation/onemkl-developer-reference-fortran/top.html .

The interfaces and implementations of Lapack and BLAS routines do not change very often; except for routines that are newly added by the maintainers of these libraries (not Intel by itself), you should be able to use documentation that is older by a year or two, and from Intel web pages or elsewhere.

Hello, thank you for the links.

I didn't receive any e-mail alert, so I missed the answer.

Thank you very much it was helpful.
