Sentence examples for using the FFTw library from inspiring English sources

The bifurcation diagram shown in Fig. 1 was computed with the library Trilinos [40] using the FFTw library to compute the FFT on the square lattice.

For the FFT based method (using the FFTW library) we see, after a decrease in the error due to the time discretization error, the characteristic linear increase in the error (see Fig. 8 top right).

This behavior is consistent across numerical libraries; in Fig. 5 results using the FFTW (Fastest Fourier Transform in the West) library and the radix-2 implementation found in GSL (GNU Scientific Library) are shown.

Frequency-domain convolution is the standard technique: take two functions, Fourier transform them (using the "FFTW" routine from MIT), take their product in Fourier space, and then back transforming the product to the spatial domain to produce the convolved result.

For a general case, we recommend using the FFTW (the fastest Fourier transform in the west) reported in [29] to compute the D ip D op DFT P s since this is the most efficient algorithm for an arbitrary length DFT.

The FT library used in the CPU implementation is the FFTW library, which is considered the most efficient in the community [22].

For each of these examples a C++ program has been written that employs the fftw library and is parallelized using OpenMP.

With this hardware support integrated with a modern microprocessor (the Alpha architecture in our experiments), the FFT performance can reap a more than twofold increase when compared against the FFTW library, a state-of-the-art implementation.

Molecular images generated using the CH5M3D library.

Using the Photos library repair tool.

Phase identification was made using the JCPDS library [35].
