二维空间中的多边形逼近。确定三个顶点a，b，c并且其函数值按从小到大排列。将二维空间中的多边形三个顶点的函数值按从小到大顺序排列， 判断三点或三点函数值的距离是否小于给定阈值.若小于阈值停止循环，得最优解x0=a(Two-dimensional space polygon approximation. Determine the three vertices a, b, c and its function value in ascending order. The three-dimensional space polygon vertices function values ​ ​ in ascending order, function to determine the three o' clock or three values ​ ​ of the distance is less than a given threshold and if less than the threshold value to stop loop, get the best solution x0 = a)

Mel-frequency cepstral coefficients (MFCCs) are coefficients that collectively make up an MFC. They are derived a type of cepstral representation of the audio clip (a nonlinear spectrum-of-a-spectrum ). The difference between the cepstrum and the mel-frequency cepstrum is that in the MFC, the frequency bands are equally spaced on the mel scale, which approximates the human auditory system s response more closely than the linearly-spaced frequency bands used in the normal cepstrum.
