用互信息作为两幅图像的相似性度量进行配准(Using mutual information as the two images of the similarity measure for registration)

移动窗口最小二乘多项式平滑，即S-G数据平滑源代码。可以滤掉光谱数据中的高频噪声，较好地保留原信号的真实性。(Savitzky-Golay Smoothing)

该源码用于分析信号的时频特性，wigner-ville分布，单信号以及两个信号间的正交wigner-ville分布(wigner-ville distribution)

binary to bcd conversion

对调制信号的频谱进行估计，通过多径和高斯白噪声的信道，解调信号的频谱和输入信号相比较(Spectrum of the modulation signal is estimated by multi-path and Gaussian white noise channel, the demodulated signal of the spectrum and compare the input signal)

用线性调频信号的雷达系统的matlab仿真(a radar system with lfm signal simulation using matlab )

对于非线性系统 如duffing和Lorenz系统，使用龙格库塔法求其系统响应，并画出相图和分岔图( For nonlinear systems such as duffing and Lorenz system, seeking its response system using Runge-Kutta method, and draw the phase diagram and bifurcation diagrams)

Nelder-Mead SIMPS = Strategy Simplex Constrained minimizer, based on iterations of full-dimensional simplex calls (Nelder-Mead direct search method), each time followed by a series of two-dimensional simplex calls (local improvements by subspaces).

空气中声传播的fdtd例程，简单可用，希望对大家有帮助(Fdtd airborne sound propagation routines, simply available, we hope to help)

使用vc6.0与matlab 2010b联合编程，并且测试通过 接口函数的编写(vc6.0 matlab 联合编程)
