Apparently you have several different versions of libblas.so.3 on your system, and it seems that the wrong one (an older one without sgemv_thread_n) is selected.

What is the output of the command

update-alternatives --display libblas.so.3

Como respuesta al comando indicado se obtuvo lo siguiente (In response to the indicated command, the following was obtained):

update-alternatives --display libblas.so.3:
===========================================

update-alternatives: error: no alternatives for libblas.so.3

Buenos días. Gracias por su tiempo.
He intentado desinstalar la librería libblas3, pero resulta imposible (parece que está siendo usada por alguna aplicación). Creo que reinstalaré el CAE LINUX para ver si se resuelve el problema.

Un abrazo.

Good Morning. Thanks for your time.
I tried to uninstall the library libblas3, but it is impossible (it seems that it is being used by some application). I think I will reinstall the CAU LINUX to see if the problem is solved.

A hug.

It seems that my command was wrong, try

update-alternatives --display libblas.so.3-x86_64-linux-gnu

Estimado Manfred Hampl

No he probado el comando sugerido porque reinstalé el CAE Linux 2018. Debido a que se requiere disco en operación para trabajar.

Ahora, después de reinstalar CAELinux, los programas Octave y Freemat funcionan perfectamente.

Gracias por su tiempo y esfuerzo.

Un abrazo desde Mendoza. Saludos.

Dear Manfred Hampl

I have not tried the suggested command because I reinstalled CAE Linux 2018. Because disk in operation is required to work.

Now, after reinstalling CAELinux, the Octave and Freemat programs work perfectly.

Thanks for your time and effort.

A hug from Mendoza. Greetings.
