清华大学数学实验之插值与拟合幻灯片与MAT源码(Tsinghua University, Experimental Math slides of interpolation and fitting with the MAT-source)

说明：  转速电流双闭环电机控制仿真，转矩脉动有些大，速度还可以。 (Current double closed-loop motor speed control simulation, some large torque ripple and speed also.)

KZK parameters.m - User-defined material/transducer parameters

2发1收STBC-OFDM系统仿真，以误码率曲线显示结果(simulation of the 2*1 STBC-OFDM systerm，the result is presented with BER-SNR curve )

实现DES算法的加，用matlab实现，代码简洁(DES algorithm to achieve the increase, with Matlab realized, concise code)

本压缩文件里面的程序是LMFnlsq2.rar里面主程序调用的一个函数，此函数不可或缺，需要联合使用。(This program inside the compressed file is LMFnlsq2. Rar inside the main program calls a function, this function is indispensable, need to use.)

一个完整的HHT程序，需要先下载EMD工具箱(A complete HHT program, you need to download the EMD Toolbox)

实现支持向量回归，能够实现小样本的回归预测分析(Regression analysis to realise the prediction base on small sample)

是一種用以衡量兩張數位影像相似程度的指標。當兩張影像其中一張為無失真影像，另一張為失真後的影像，二者的結構相似性可以看成是失真影像的影像品質衡量指標。(Is a digital image to measure the similarity of two indicators. Two images when one of them is undistorted image and one for image distortion after the structural similarity between the two images can be viewed as a measure of the quality of the image distortion.)

用matlab绘出螺旋曲线上升的动态效果(Draw the dynamic effect of the spiral curve rises)
