# This Makefile.am specifies a set of codelets, efficient transforms
|
||
|
|
# of small sizes, that are used as building blocks (kernels) by FFTW
|
||
|
|
# to build up large transforms, as well as the options for generating
|
||
|
|
# and compiling them.
|
||
|
|
|
||
|
|
# You can customize FFTW for special needs, e.g. to handle certain
|
||
|
|
# sizes more efficiently, by adding new codelets to the lists of those
|
||
|
|
# included by default. If you change the list of codelets, any new
|
||
|
|
# ones you added will be automatically generated when you run the
|
||
|
|
# bootstrap script (see "Generating your own code" in the FFTW
|
||
|
|
# manual).
