The market price of a good is determined by both the supply and demand for it, so the economic model is very important for the consumers and the suppliers, and then we need a way to measure this model. This report is an attempt to give us some ideas about linear static model and how to use it in market model. We will use first analytical method to find the relationship between the price and quantity, then we find the equilibrium price for the market model by using numerical method

Compressive Sampling是最近讨论非常热烈的数据处理方法。用一个与变换基不相关的观测矩阵将变换所得到的高维信号投影到一个低维空间上，然后通过优化求解从这些少量的投影中以高概率重构出原信号。(Compressive Sampling is a very lively discussion of recent data processing method. A base with the transformation matrix will not change the relevant observation obtained a high-dimensional signal projected onto low-dimensional space, and then solved by optimizing the projection from these small reconstructed with high probability in the original signal.)

matlab中实现商品的数值分析，分析商店的月销售额，季度的销售额什么的，是比较基础的matlab程序(matlab to achieve numerical analysis merchandise, store monthly sales analysis, quarterly sales in what is a relatively basic matlab program)

说明：  基于旋转不变技术的信号参数估计”,同样的，和Musci,Root-Music算法一样，这类基于相关矩阵特征分解的信号频率估计方法(Signal parameter estimation based on rotation invariance technology ", similarly, like music and root music algorithms, this kind of signal frequency estimation method based on correlation matrix eigendecomposition)

MATLAB工具箱的简介,人工智能的工具箱,希望对大家有用(About MATLAB toolbox, artificial intelligence of the toolbox, in the hope that useful)

A semi blind technique for estimating the carrier frequency offset in OFDM communication systems is presented in this paper. The fractional and integer frequency offsets are esti-mated by employing a few null subcarriers in the rst OFDM symbol in a frame. While the conventional null subcarrier based methods estimate the offset by a single global search, the proposed method employs a two stage estimator, which greatly minimize the computational complexity.
