makefile

一个完整FFT变换的C代码, 本代码在工程项目中得到了应用的检验. 若哪位发现BUG请通知本人.

#				Makefile
# 	to build and test the Numerical Math Library (libla.a)
#
# To build the library, you may want to edit the list of library modules
# below (MODULES). Say, if you don't need/want FFT, remove all the names
# that contain fft from MODULES=. Then point ./c++ to the right
# script: g++.2.7.2 or g++.2.8.1 (see below if using a non-GNU C++ compiler).
# Then make the modules you chose:
#		make lib
# A simple 'make' would suffice, too.
#
# To verify the library, do
#	make check-all
# or, specifically,
#	make vmatrix		(checks elementary matrix operations)
#	make vmatrix1		(checks less trivial matrix operations)
#	make vmatrix2		(checks advanced matrix operations: multipl)
#	make vlastreams		(checks treams over matrices and vectors)
#	make vvector		(checks elementary vector operations)
#	
#	make vzeroin		(verifies Brent's 1D root finder)
#	make vfminbr		(verifies Brent's 1D minimizer)
#
#	make vali		(check Aitken-Langrange interpolators)
#	make vhjmin		(check a multi-variate optimizer)
#
#	make vsvd		(check SVD decompositions)
#	make vslesing		(test solving generalized Ax=b)
#
#	make vfft		(check and clock FFT)
#
#	make sample_ult
#	make sample_adv
# Note, this Makefile was built (and works under) GNU make 3.71
#
# Please check RANLIB below and adjust it for your system if necessary
# (it was made for a BSD-like system)
