nbcspline[1]

说明：  用matlab 写的将avi电影转化成BMP图像序列，调试通过的(Avi movie to convert BMP image sequences)

commande and control the qudrirotor

两个函数都是用hopfield神经网络实现4位的A/D转换。采用不同的结构得到不同的结果(Parallel structure.)

说明：  通过Monte Carlo仿真，说明DS扩频信号在抑制正弦干扰方面的有效性。用一均匀随机数发生器产生某个二进制信息符号的序列，每个信息比特重复Lc次。 包含文件：DS_restrain_interference.M SS.M(through Monte Carlo simulation, note DS spread spectrum signal sinusoidal interference in inhibiting the effectiveness. Using a uniform random number generator produce a binary sequence information symbols, each bit of information to repeat Lc times. Documents include : DS_restrain_interference.M SS.M)

二阶Butterworth滤波器, 可以直接用于数字信号处理，里面有输入输出说明，很详细(Second Order Butterworth Band-Pass Filter)

雷达交叉定位精度分析，CRB界确定，寻求最远定位距离！(Radar cross positioning accuracy analysis, CRB sector determined to seek the farthest distance positioning!)

图像的平面微分平方和能够反映图像高频分 量的能量。用计算平面微分平方和的方法在空间域上计算相邻像素亮度差值的平方和，对应于在频率域上计算图像高频分量的能量和，此值越大，图像对焦越准确(Differential square image plane and the image can reflect the energy of high frequency. Computational method of Planar Differential squares calculated in the space domain to the square of the difference between the brightness of adjacent pixels and corresponds to the image in the frequency domain calculation of high frequency energy and, this value is larger, the more accurate the image focus)

用窗函数设计数字滤波器，对所给出的含有噪声的声音信号进行数字滤波处理，得到降噪的声音信号，并进行播放试听。(Digital filter design, the sound signal containing noise given digital filter processing sound signal to reduce noise and play audition.)

说明：  非参数贝叶斯工具箱，用于matlab，附带HMM学习过程(Nonparametric Bayesian toolbox)

Newton-Armijo code for scalar equations: Inputs: X = initial iterate, F = function, TOLA = absolute error tolerance, TOLR = relative error tolerance, JDIFF = 0, analytic derivative, syntax: [f,fp]=f(x), JDIFF = 1, forward difference derivative , Output: x=approximate result, HIST = array of iteration history
