How To Install fftw2-devel on CentOS 7
Introduction
In this tutorial we learn how to install fftw2-devel on CentOS 7.
What is fftw2-devel
FFTW is a C subroutine library for computing the Discrete Fourier Transform (DFT) in one or more dimensions, of both real and complex data, and of arbitrary input size. We believe that FFTW, which is free software, should become the FFT library of choice for most applications. Our benchmarks, performed on on a variety of platforms, show that FFTW’s performance is typically superior to that of other publicly available FFT software. This package contains header files and development libraries needed to develop programs using the FFTW fast Fourier transform library version 2.
We can use yum or dnf to install fftw2-devel on CentOS 7. In this tutorial we discuss both methods but you only need to choose one of method to install fftw2-devel.
