makefile.am

用于DFT计算的c语言的库的最新版本,包含丰富的函数库.

# 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).
