 your arrays (see <a href="Allocating-aligned-memory-in-Fortran.html">Allocating aligned memory in Fortran</a>). Alternatively, you can
use the <code>FFTW_UNALIGNED</code> flag when creating the
plan, in which case the plan does not depend on the alignment, but
this may sacrifice substantial performance on architectures (like x86)
with SIMD instructions (see <a href="SIMD-alignment-and-fftw_005fmalloc.html">SIMD alignment and fftw_malloc</a>).
