stanford大学deep learning在线课程课后练习代码，我自己写的，可以参考一下。(Excercise of deep learning online course from http://deeplearning.stanford.edu/wiki. It is written by myself, aiming to help other students who is confused in the course.)

数值解与理论解对比可知，四阶龙格-库塔法的精度已经很高，用它来解一般常微分方程已经足够了。(Numerical comparison shows that the theoretical solutions, Runge- Kutta method has high accuracy, and use it to solve ordinary differential equations general enough.)

基于MVDR算法，计算两个信号的相关性的函数。(This program computes the coherence function between 2 signals x1 and x2 with the MVDR method. This algorithm is based on the paper by the same authors: J. Benesty, J. Chen, and Y. Huang, "A generalized MVDR spectrum," IEEE Signal Processing letters, vol. 12, pp. 827-830, Dec. 2005. x1, first signal vector of length n x2, second signal vector of length n L is the length of MVDR filter or window length K is the resolution (the higher K, the better the resolution))

说明：  《MATLAB图形技术——绘图及图形用户接口》西北工业大学出版社，1999年版，周明等编著。介绍了matlab绘图方法和图形对象的特性及图形用户接口的设计技术。(MATLAB graphics- drawing and graphical user interface, Northwest Industry University Press, 1999 edition, Zhou Ming, eds. Introduced matlab drawing method and graphic object properties and the graphical user interface design.)

说明：  应用matlab进行数字信号处理的一些源代码，希望对大家有帮助。(Matlab applications for digital signal processing of the source code, and I hope to be helpful.)

Radical basic function to predict

this is a matlab/simulink simulation for the direct adaptive fuzzy control of the inverted pendilum.

IDW距离反比加权方法，权重选择为2，可根据需要自己改变(IDW inverse distance weighting, the weight chosen as 2, can be changed according to need their own)

本文件详细描述了如何利用matlab去检测图片中含有的直线元素，利用hough变换。(This document describes in detail how to use matlab to detect images containing linear elements using hough transform.)
