在matlab环境下实现对MP3文件的读写，(read the MP3 in the matlab)

基于matlab的数字图像的二维傅立叶变换(FFT)以及二维离散余弦DCT变换，提供里详细代码，.m文件(Matlab-based digital image two-dimensional Fourier transform (FFT) and two-dimensional discrete cosine transform DCT offers in detailed code,. M file)

四元数表示的，用于matlab仿真的工具箱。通过它，可以掌握四元数的一些特征。(quaternion said, for the simulation of Matlab Toolbox. Through it, we can get quaternion some characteristics.)

Matlab画平滑曲线的两种方法（ 拟合或插值后再用plot即可） 自然状态下，用plot画的是折线，而不是平滑曲线。有两种方法可以画平滑曲线，第一种是拟合的方法，第二种是用spcrv，其实原理应该都一样就是插值。下面是源程序。(You can then use the plot) Natural state, with the plot is a line drawing, instead of a smooth curve. There are two ways to draw a smooth curve, the first one is the fitting method, and the second is to use spcrv, in fact, the same principle should be that the interpolation. Here is the source.)

LCL滤波器在现代的可再生能源行业的应用十分的普遍，可以有效、经济地确保和提高从能源到电网的馈电质量。滤波器用于过滤逆变器工作产生的开关频率。在达到目标畸变水平的同时，滤波器还会节约比较可观的成本。LCL滤波器的典型特点是损失小、体积小、重量轻、电容大。(LCL filter in the application of modern renewable energy industry is very common, can be effectively and economically to ensure and improve the quality of energy to the grid feed. This filter is used to filter the inverter switching frequency. The filter will reach the target distortion level at the same time, considerable cost savings. LCL filter typically characterized by loss, small size, light weight, large capacitance.)

实现地震叠前三参数反演（纵波速度、横波速度、密度。本程序是基于matlab编写的。(Stack seismic inversion to achieve the first three parameters (P-wave velocity, shear wave velocity, density. This program is based on matlab prepared.)

its matlab code for lane detection algorithm for intelligent highway

数值分析中，用弦截方法求解方程的根 (Numerical analysis, the strings cut method for solving equations with roots)

基于matlab卡尔曼滤波源代码，导入数据，可以运行(Calman filter source code based on.If you import the data, it can run.)

qpsk的调制解调源码，注释详细。功能正常。很适合学习调制解调的人.文件包含： qpsk_mod_demod.m(qpsk mod and demod procedure qpsk_mod_demod.m)
