60 <p>This section describes the format in which multi-dimensional arrays
|
|
cannam@95
|
61 are stored in FFTW. We felt that a detailed discussion of this topic
|
|
cannam@95
|
62 was necessary. Since several different formats are common, this topic
|
|
cannam@95
|
63 is often a source of confusion.
