this is the code for fast fourier transform. there are also code for ifft,invfft......

利用回溯法来求解凸函数的最优值。采用非精确线性搜索，利用最少的迭代次数找到最优值。(backtracking method，change the step size in searching procesure and finally find the optimizaiton points. )

matlab code for calibrated parametric equalizer

双线性内插,图像放大缩小，简单容易学，好理解，上手快(Bilinear interpolation, image zoom, simple and easy to learn, easy to understand, quick)

对具有随机噪声的二阶系统的模型辨识，进行标幺化以后系统的参考模型差分方程为 (7.90) 式中， 为随机噪声。由于神经网络的输出最大为1，所以，被辨识的系统应先标幺化，这里标幺化系数为5。利用图7.5正向建模(并联辨识)结构，神经网络选用3-9-9-1型，即输入层i，隐层j包括2级，输出层k的节点个数分别为3、9、9、1个； (Model identification of two order systems with stochastic noise)
