compute_curvature

粒子群算法的改进，粒子在搜索过程中，适应值大的部分粒子，运动方向反方向运动，扩大了搜索范围，避免早熟。通过函数测试可用。(Particle swarm algorithm, part of the particle motion direction opposite direction, expanding the scope of the search to avoid premature. Through function test available.)

it is a implementation of a chaotic map.the chaotic map nam is logistic map

信噪比=20，迭代步长=0.035，本次程序设计还是验证了RLS比LMS收敛快的效果。(SNR = 20, iteration step = 0.035, this program is designed to verify the RLS faster than the LMS convergence effect.)

对已知的以为数据进行FFT变换，得到数据的频谱图，进而可分析出幅值和相角。(Known that the data FFT, the frequency spectrum of the data, which can be analyzed magnitude and phase angle.)
