一个出售卡片信息的源码 是我的一个作业，和大家分析一下(a sale card information source was one of my operations, and we analyze)

一中Ldpc编码，使用matlab实现的，采用的是线性编码算法，复杂度为线性(One Ldpc code, the use of matlab implementation, using a linear encoding algorithm complexity is linear)

说明：  This file contains the Matlab codes for non-linear estimation of Nelson-Siegel Model

三相滞环电路控制模块，用以实现输出电压电流偏差矫正(Three-phase hysteresis circuit control module to achieve the correct output voltage and current bias)

the attached utility is a work I ve submitted to the university It shows what a jpeg compression is all about. the function implements the DCT transform, using a matrix operator. note that matlab has a function for the DCT and iDCT transforms that might be more efficient.(the attached utility is a work I ve submitted to the universityIt shows what a jpeg compression is all about.the function implements the DCT transform, using a matrix operator.note that matlab has a function for the DCT and iDCT transforms that might be more efficient .)

说明：  使用BP算法实现异或功能，由matlab编程实现，可正确运行。(BP algorithm using the XOR function, the matlab programming, can be run correctly.)

多项式和非多项式曲线拟合，多项式拟合在matlab中可以使用polyfit函数求解多项式系数，通过polyval函数求解拟合多项式在某数据点处的值(Polynomial and non-polynomial curve fitting, polynomial fitting in matlab polyfit function can be used to solve polynomial coefficients, solve the value of a data point to fit a polynomial function by polyval)

仿真效果非常好，本科毕设要求参见标准测试模型，脉冲响应的相关分析算法并检验。( Simulation of the effect is very good, Undergraduate complete set requirements refer to the standard test models, Related impulse response analysis algorithm and inspection.)
