CPPsimplex
单纯形法,求解线性规划问题的通用方法。单纯形是美国数学家G.B.丹齐克于1947年首先提出来的。它的理论根据是:线性规划问题的可行域是 n维向量空间Rn中的多面凸集,其最优值如果存在必在该凸集的某顶点处达到。顶点所对应的可行解称为基本可行解。单纯形法的基本思想是:先找出一个基本可行解,对它进行鉴别,看是否是最优解;若不是,则按照一定法则转换到另一改进的基本可行解,再鉴别;若仍不是,则再转换,按此重复进行。因基本可行解的个数有限,故经有限次转换必能得出问题的最优解。如果问题无最优解也可用此法判别。

KFFT
计算离散傅里叶变换的一种快速算法,简称FFT。快速傅里叶变换是1965年由J.W.库利和T.W.图基提出的。采用这种算法能使计算机计算离散傅里叶变换所需要的乘法次数大为减少,特别是被变换的抽样点数N越多,FFT算法计算量的节省就越显著。(A computing discrete Fourier transform fast algorithm, referred to as FFT. Fast Fourier Transform in 1965 by the JW Cooley and TW Tuji Ti out. Using this algorithm enables a computer to calculate the number of multiplications needed for the discrete Fourier transform greatly reduced, especially sampling points N is transformed more and save FFT algorithm to calculate the amount of the more remarkable.)
