牛顿迭代法求非线性方程的解，需输入初始值，方程，导数方程，步数，error(Newton iteration solution of nonlinear equations required to enter the initial value equation, derivative equation, step number, error)

it is one type of Particle Swarm Optimization(PSO). A recently reported successful PSO variant is the comprehensive learning particle swarm optimization (CLPSO) where each dimension of a particle is updated separately by following an exemplar particle relatively fitter in the corresponding dimension

耳蜗实质上相当于一个滤波器组，耳蜗的滤波作用是在对数频率尺度上进行的，在1000HZ下，人耳的感知能力与频率成线性关系；而在1000HZ以上，人耳的感知能力与频率不构成线性关系，而更偏向于对数关系，这就使得人耳对低频信号比高频信号更敏感。Mel频率的提出是为了方便人耳对不同频率语音的感知特性的研究。频率与Mel频率的转换公式为(on logarithm frequency scale, under the 1000 hz, the perception of the human ear and a linear relationship with frequency In more than 1000 hz, the perception of the human ear does not constitute a linear relationship with frequency, and prefer to logarithmic relationship, which makes the human ear is sensitive to low frequency signal is better than high frequency signal. Mel frequency is put forward in order to facilitate the ear of the study of speech perception characteristics of different frequency. For frequency and Mel frequency conversion formula )
