读取图片的RGB信息，进而转换为HSV，最后作出颜色直方图(Reads the image information of RGB, and then converted to HSV, and finally make the color histogram)

java画板，对图形编程有比较好的借鉴作用。画板的基本功能基本都有(java huaban)

PSCAD下调用matlab进行傅里叶分析的实例。因节点数超过15个，需要高于在学生版PSCAD中运行。(Example case for fourier analysis calulation using MATLAB.This case will not run on the Student Edition of PSCAD because it has more than 15 nodes! )

MFC 画出简单的坐标 并通过按钮产生随机点坐标（横坐标逐渐增大纵坐标随机）存入文件中 另一按钮实现读出数据并将点连成折线(MFC drawing simple coordinate and through the button generates random point coordinates (abscissa increases ordinate random) into a file and another button to achieve read data points connected into line)

可以批量绘制全潮海流观测的流速流向曲线图,以大潮为例.只需将观测数据写为xlsx格式,即可自动出图.可以支持多个xlsx文件批量绘制.(You can draw all tidal currents observed mass flow rate of the flow graph to tide Case observational data simply written as xlsx format, you can automatically plot can support multiple xlsx file batch rendering.)

PSCAD做的12模块H桥SVG模型，电流矢量控制，运行良好。(PSCAD do SVG module 12 H bridge model, the current vector control, work well.)

matlab绘图中柱状图增加图案，用于区分不同柱状图(matlab drawing increased histogram pattern is used to distinguish between different histogram )
