| 59 double *in, const int *inembed, | |
| 60 int istride, int idist, | |

| 66 Like <code>fftw_plan_many_dft</code>, this functions adds <code>howmany</code>, | |
| 67 <code>nembed</code>, <code>stride</code>, and <code>dist</code> parameters to the | |
| 68 <code>fftw_plan_r2r</code> function, but otherwise behave the same as the | |
| 69 basic interface. The interpretation of those additional parameters are | |
| 70 the same as for <code>fftw_plan_many_dft</code>. (Of course, the | |
| 71 <code>stride</code> and <code>dist</code> parameters are now in units of | |
| 72 <code>double</code>, not <code>fftw_complex</code>.) | |
| 73 | |
| 74 <p>Arrays <code>n</code>, <code>inembed</code>, <code>onembed</code>, and <code>kind</code> are not | |
| 75 used after this function returns. You can safely free or reuse them. | |
