说明：  用于数字图像相关方法中散斑质量评价，评价标准之一是平均灰度梯度，此压缩包中包含了如何形成高斯分布的数字散斑以及用于计算不同子区大小的平均灰度梯度值(For speckle quality evaluation in digital image correlation method, one of the evaluation criteria is the average gray gradient. The compression package contains how to form a Gaussian digital speckle distribution and the average gray gradient value used to calculate the size of different subareas)

关于matlab的几篇学习资料,提供给大家一起分享,谢谢大家啊!! (Matlab on a few learning materials available to share, thank you ah!!)

对模型预测控制原理的详细讲解，强烈推荐新手如门学习(description for MPC in detail)

非常详细的ofdm系统matlab程序。。。。。。。。(Matlab ofdm system very detailed procedures)

matlab建模的百科全书，司守奎老师编著的(many useful knowledge about matlab )

设计一个采用 2ASK（OOK）调制的数字通信系统，给定载波频率为码元速率的2倍，产生二进制随机数据，并仿真其对应的 2ASK 调制波形，分析其频谱。所产生的调制波形加入不同信噪比的白噪声，再观察其波形和频谱变化。(Design of a use 2ASK (OOK) modulated digital communication system, a given carrier frequency is twice the symbol rate, to generate a random binary data, and simulate its corresponding 2ASK modulation waveform, the spectrum analysis. Modulated waveform generated by white noise with different noise ratio, and then observe its waveform and spectrum changes.)

实现希尔伯特-黄变换的功能，并带有一段测试数据。希尔伯特-黄变换是使用EMD分解将信号分解为本征模态函数（IMF），然后求得IMF分量的瞬时频率。其对于非稳态和非线性信号具有优良的效果。(The function plot_hht is a realization of the Hilbert-Huang transform (HHT). The HHT decomposes a signal into intrinsic mode functions (or IMFs), and obtain the instantaneous frequency data. It is designed to work well for data that are nonstationary and nonlinear.)
