本程产生了二进制相位调制脉冲压缩信号，在mimo雷达信号编码中有所应用(This process produces a binary phase modulation pulse compression signal mimo radar signal coding has been applied)

COMPARISON OF MEAN AND MEDIAN FILTER METHOD

This m-file applies uniform quantization on audio signal and produced the Mean Square Quantization Error

An effective undergraduate controls curriculum will have strongly coupled laboratory and classroom components. It is important that the students experience the application of the classroom theory. Mathwork’s Simulink environment is ideal for teaching modeling and simulation of feedback control systems

几何活动轮廓的matlab程序，可用性强，写的很好。(Geometric active contour the matlab program, availability, and write well.)

最短路这个说明倒不是说明函数的功能，只是声明一下函数中出现的问题。 shortest()函数没有问题，在secshortest中我希望只得到一条次短路（或几条roadcost()值相同的次短路），结果却出来好几条，我仔细检查了一下程序，应该没有什么问题。 因此在使用时，要得到次短路，只能用roadcost()函数分别求一下各条路的权重和，找到最小的。 有些奇怪 (short path)

梯度下降法是一個一階最佳化算法，通常也稱為最速下降法。 要使用梯度下降法找到一個函數的局部極小值，必須向函數上當前點對應梯度（或者是近似梯度）的反方向的規定步長距離點進行疊代搜索。如果相反地向梯度正方向疊代進行搜索，則會接近函數的局部極大值點；這個過程則被稱為梯度上升法。(The gradient descent method is a first-order optimization algorithm, also commonly referred to as the steepest descent method. To find the local minimum of a function using the gradient descent method, an iterative search must be performed to the specified step distance point in the opposite direction of the gradient (or approximate gradient) of the current point on the function. If the search is reversed in the opposite direction to the positive direction of the gradient, it will approach the local maximum point of the function; this process is called the gradient ascent method.)
