说明：  基于内容的图像检索主颜色直方图的提取，从图像的获取到直方图现实到特征的提取，最后根据图像检索出与所给图像最相似的图像。(Content-based image retrieval dominant color histogram extracted from the images to get to the real histogram feature extraction, the last based on the image to retrieve the image with the most similar images.)

步进频雷达脉冲信号，设置了起始截止频率，步进频率，脉宽等等参数，简单易懂(Stepping frequency radar pulse signal, set the initial cutoff frequency, step frequency, pulse width, etc. parameters, easy to understand)

It is a three dimensional interpolation with tricubic convolution interpolation,which is the method used in Matlab.But, it is more useful and faster the the code implement by Matlab.

用于智能天线原理演示（一维直线阵） 生成的指向性波束在主瓣方向与其他方向的功率对比(used for demostration of amart antenna（1-dimension straight array） to compare the power within the main lobe and other direction of the generated directional beam )

最小均方误差（MMSE）的算法，多姿态，多角度，有不同光照,包括调制，解调，信噪比计算。( Minimum mean square error (MMSE) algorithm, Much posture, multi-angle, have different light, Includes the modulation, demodulation, signal to noise ratio calculation.)

元胞自动机的matlab程序。 元胞自动机（CA）是一种用来仿真局部规则和局部联系的方法。典型的元胞自动机是定义在网格上的，每一个点上的网格代表一个元胞与一种有限的状态。变化规则适用于每一个元胞并且同时进行。典型的变化规则，决定于元胞的状态，以及其（ 4或8 ）邻居的状态。元胞自动机已被应用于物理模拟，生物模拟等领域。(Cellular Automata matlab procedures. Cellular Automata (CA) is a simulation used to contact the local rules and local approach. A typical cellular automaton is defined in the grid, each grid point represents a cell with a limited state. Changes in the rules applicable to each cell and at the same time. Typical changes in the rules of decision in the cellular state, as well as its (4 or 8) neighbor state. Cellular Automata have been used in physical simulation, biological simulation and other fields.)
