根据已给数据，画出风场示意图。有图例，方向。(draw wind field)

数值方法和MATLAB的实现与应用，翻译版本。原版(Numerical methods and MATLAB Implementation and Application, translation. Original edition)

this is matlab book on digital signal processing.

matlab的两个小球碰撞的模拟程序，很简单的。平时没事瞎编的。(Two small ball collision matlab simulation program, very simple. Usually nothing fabricated.)

UWB，超宽带信号分析必用的子函数，第6部分！(UWB, ultra-wideband signal analysis will be used for Functions, Part 6!)

部分神经元的连线图,画图程序drawing 画神经元连线(draw neurons connection)

对预处理及分割之后的图像进行识别 利用BP神经网络进行训练 学习(On after pretreatment and segmentation of image recognition using BP neural network for training study)

说明：  第三章 程序流程控制 主要内容1、if…else…选择语句。 2、条件运算符。 3、SWITCH开关分支语句。 4、逻辑运算符。 5、循环语句。 6、自增自减运算。 7、break、continue、goto语句 8、运算符的优先级、结合性。(Chapter III of the main contents of the control procedures for flow 1, if ... else ... select statement. 2, conditional operator. 3, SWITCH branch switch statements. 4, the logical operator. 5, loop. 6, since by reducing computing since. 7, break, continue, goto statement 8, the priority of operator, combined with nature.)

MATLAB编写利用P-Q分解法的潮流计算程序，程序中利用基于稀疏技术的因子表法进行迭代求解，以降低存储量，提高运算速度。本程序只适用于简单系统，如IEEE5节点系统。对于复杂系统，由于PV节点电压越限等问题尚未考虑，得到的潮流结果可能有误！(MATLAB flow calculation program written using PQ decomposition method, program utilization based on sparse iterative solver technology factor table method to reduce the storage capacity, improve processing speed. This procedure applies only to simple systems, such as IEEE5 node system. For complex systems, PV node voltage due to the more limited issues not yet considered, the trend of the results obtained might be wrong!)

this package allows to solve to incompressible Navier-Stokes equations with a fast method
