lt码的编译码，译码方式为bp译码，源码的比特数可以自己设定(lt code encoding and decoding, decoding method for the bp coding, source bits can be set)

说明：  四阶Runge-Kutta法解常微分方程组(Fourth Order Runge-Kutta Method for Solving Ordinary Differential Equations)

改进平方根法求解对称正定线性方程组，用matlab编写，可以在一定程度上提高求解效率。其中MRoot_squaring.m为原做法，sparse_cmp.m为二维等带宽存储，Moot_zonal.m为二维等带宽存储的平方根法求解(To improve the square root method to solve symmetric positive definite system of linear equations using matlab to prepare, to a certain extent improve the efficiency of solving. MRoot_squaring.m which the original approach, sparse_cmp.m for the two-dimensional, such as memory bandwidth, Moot_zonal.m for the two-dimensional, such as the square root of bandwidth storage method)

matlab扩展编程：增加了matlab的数据结构和编程技巧，c调用matlab，matlab访问硬件系统，matlab录音工具，matlab的语音识别系统等(matlab expand programming: an increase of matlab data structures and programming techniques, c call matlab, matlab access to hardware system, matlab recording tools, matlab voice recognition systems, etc.)

利用小波变换进行图像去噪的程序 基于MATLAB的(Image denoising using wavelet transform procedures for MATLAB-based)

fft谐波检测，分析信号的频谱和幅值，相位(fft harmonic detection, analysis of the signal spectrum and amplitude, phase)

MPCA程序，用于人脸特征提取，很有用，欢迎交流探讨(MPCA program for facial feature extraction, is useful, welcomed the exchange of)

a exponential principal component analysis code.......

说明：  matlab GUI 计算器，和附件的计算器功能类似，由GUI实现(matlab GUI calculator, calculator functions and accessories similar to the GUI to achieve)

故障诊断，包络解调分析，对于轴承故障诊断非常有效(Fault diagnosis, envelope demodulation, very effective for bearing fault diagnosis)
