.Sparse coding algorithm.We can also apply it onefficient sparse coding algorithm to a new machine learning framework called "self-taught learning", where we are given a small amount of labeled data for a supervised learning task, and lots of additional unlabeled data that does not share the labels of the supervised problem and does not arise from the same distribution.

说明：  用matlab平台实现的拉格朗日插值算法（另附一个插值算法）(Matlab platform with the Lagrange interpolation algorithm (followed by an interpolation algorithm))

电路 信号系统仿真的源码 基于multisim10.0(Signal System Simulation multisim10.0 based on the source)

洛伦兹吸引子的函数程序以及动态图形，matlab程序(Lorenz attractor function procedures and dynamic graphics, matlab program)

对一个信号进行奇异值分解，根据差分谱最大值点，重构信号，达到降噪的目的。(Signal for a singular value decomposition, according to the differential spectrum maximum point, the reconstructed signal to achieve noise reduction purposes.)

AR模型功率谱估计,Matlab环境,估计效果较好.(AR model for power spectrum estimation, Matlab environment, it is estimated better.)

本程序由一对m序列优选对模二加生成一组平衡GOLD序列码，用于对直扩系统仿真之中，通过改变第二个m序列的初始状态可以生成不同的GOLD序列码(The program consists of a pair of m sequence optimization of mode two and generate a set of balanced GOLD sequence codes for DSSS system simulation, by changing the initial state of second m sequences can generate GOLD sequence code different)

optical character recognition is used to convert images of any paper into soft copies

说明：  自适应共振理论网络 用来进行模式分类联想记忆效果很好，误差率极低，能正确识别(Adaptive Resonance Theory networks used for pattern classification associative memory with good results, the error rate is very low, able to correctly identify)

this is the matlab code for a simple PLL circuit "Phase Locked Loop"
