这是我自己写的对图像进行预处理的matlab源程序，主要是对图像进行光照补偿、旋转与尺度归一化。上传上来和大家一起学习、分享。(This is I wrote it myself pretreatment image matlab source, mainly for image illumination compensation, rotation and scale normalized. From up and study together, to share.)

提供了4-psk的matlab源程序包，包括主函数和子函数，可供初学者学习参考。(Provides a 4-psk the matlab source code package, including the main function and Functions for beginners to learn the reference.)

经典的标量JA 模型的代码，非常适合磁滞模型初学者 我给出了两种实现方式的代码 一个用固定点迭代实现，可以容易变成c语言 另一个使用simulink 实现，可以加到控制图中作为一个子函数(the code is programmed following the classical paper of D.Jiles ,fellow of IEEE. The JA model is great and innovative work in magnetic material.)

当波导和介质偶合时,计算波传导过程中的透过率,反射率.(when waveguide coupling and the media, the calculation of the conduction process of transmittance, reflectance.)

总体X服从非中心卡方分布，求两个参数的极大似然估计 输入：样本数据 输出：参数估计值n，v 内有详细说明(Overall X obey non-central chi-square distribution, find the two parameters MLE)

matlab与外部程序接口技术，想进一步学习matlab的好资料。(matlab with the external program interface technology, to further study matlab good information.)

matlab编写的信号分解，采用HHT变换的EMD分解方法，提取信号的各阶EMD分量。(matlab write signal decomposition, the use of HHT transform EMD decomposition method to extract the signal component of each order EMD.)
