33 FFTW is a C subroutine library for computing the discrete Fourier
34 transform (DFT) in one or more dimensions, of arbitrary input size, and
35 of both real and complex data (as well as of even/odd data, i.e. the
36 discrete cosine/sine transforms or DCT/DST).

85 <para>
86 We build fftw three times for different libraries in different
87 numerical precisions: the default double precision floating point, the
88 older 32-bit (single precision) version named float which sacrifices
89 precision for speed, and the long double which offers increased
90 precision at the cost of slower execution.
91 </para>
92 </note>
93
94 <para>
95 The first build is for double precision arithmetic. Install
96 <application>fftw</application> by running the following commands:

106
107 <para>
108 To test the results, issue: <command>make check</command>.
109 On 32-bit systems, the tests can take substantially longer than
110 they would on 64-bit machines.
