ldpc codes codec procedures, very good for learning ldpc.

在离散数据的基础上补插连续函数，使得这条连续曲线通过全部给定的离散数据点。插值是离散函数逼近的重要方法，利用它可通过函数在有限个点处的取值状况，估算出函数在其他点处的近似值。插值：用来填充图像变换时像素之间的空隙。(On the basis of discrete data, a continuous function is inserted to make the continuous curve pass through all the given discrete data points. Interpolation is an important method of approximation of discrete functions. It can be used to estimate the approximate values of functions at other points by means of the values of the functions at finite points. Interpolation: used to fill the space between pixels when an image is transformed.)

本程序是现代谱导航分析中的惯性导航误差分析matlab程序，经过仿真验证，获得较为准确的结果。(The navigation program is modern spectral analysis of inertial navigation error analysis matlab program, through simulation, to obtain more accurate results.)

各种数据处理的基本算法，包括最小二乘，和各种算法与最小二乘的算法融合(Basic Algorithms for Various Data)

本程序用来模拟当前研究很热门的自旋阀满足的LLG方程，并作图研究其性态。具体数据公式文件包里有详细说明(the procedures used to simulate the current research is very popular spin valves to meet the LLG equation, and mapping study its behavior. Specific data document bundle formula are described in detail)

汽车七自由度的振动程序，可以求解固有频率，悬架的动挠度等，欢迎大家下载学习与交流(vibration of the car with seven degrees)

this is a good book to learn the matlab. from here , you can learn a lot idea about write the matlab code.

it is cluster1 matlab code
