conjugate gradient algorithm for multivariable functions

说明：  拟合各种常见分布程序，产检的威布尔分布，瑞利分布，K分布等分布，采用语言为matlab。(Fitting a variety of common distribution procedures, check-Weibull distribution, Rayleigh distribution, K distribution of the distribution, the use of language matlab.)

1. 图像二值化 2. 边界跟踪，去除离散点 3. 边界提取 4. 删除短边 5. 区分河流与道路 先找到桥梁，利用桥梁上的种子点 对道路进行跟踪，从而提取整条主干道。 (1 image binarization 2boundary tracking, removal of discrete points 3 boundary extraction 4 Remove the short side 5 distinguish rivers and roads the curvature is too large) First find the bridge, the bridge on the use of seed points on the road to follow, thereby extracting the whole trunk.)

用ode45求解悬臂梁的动力学方程，得到其变形(Use ode45 solving the dynamic equation of the beam, to get its deformation)

matlab神经网络newff函数用来创建网络，为BP神经网络设置参数(newff is very important of BP.)

it shows the Antenna Directivity Pattern by using matlab

基于电流滞环比较器的PMSM调速控制，通过对电流的滞环控制，达到控制转矩的目的。控制效果好！(PMSM speed control based on current hysteresis comparator, current hysteresis control, to achieve the purpose of the control torque. Control effect is good!)
