FFTW3 Setup and library environment variable settings (path setting)

This article is a problem encountered in the installation of Nlsartoolbox, mainly the installation of fftw3f.

For path and environment variable configuration, refer to the link

Tips for Linux

Official Ubuntu Help

Recommended ways to add paths (setting environment variables):

Add a path in ~/.profile

Export path= $PATH:/newpath

And then

SOURCE ~/.profile

Make it effective immediately.

However, the problem is not on the environment variable, but the fftw3f installation is unsuccessful.

Lapack by installation

Open a terminal and type

sudo apt-get install Liblapack-dev
