| 57 | |
| 58 <p><a name="index-Fortran-interface-331"></a> | |
| 59 This chapter describes the Fortran-callable interface to FFTW, which | |
| 60 differs from the C interface only in the prefix (`<samp><span class="samp">dfftw_</span></samp>' instead | |
| 61 of `<samp><span class="samp">fftw_</span></samp>'), and a few other minor details. The Fortran interface | |
| 62 is included in the FFTW libraries by default, unless a Fortran compiler | |
| 63 isn't found on your system or <code>--disable-fortran</code> is included in | |
| 64 the <code>configure</code> flags. We assume here that the reader is already | |
| 65 familiar with the usage of FFTW in C, as described elsewhere in this | |
| 66 manual. | |
