CAD

利用mathcad编写的特定谐波消去法的仿真程序，并且可以给出shepwm图形(To mathcad written in a specific harmonic elimination method simulation program, and can give shepwm graphics )

实现大量数据，选择多项式模型进行曲线拟合,获取数据输入输出见的非线性关系(curve_ matching)

本程序基于滑动窗口可以实现对一维曲线平滑及降噪，根据有用信号的频率，选取合适的窗口宽度。(This procedure can be achieved based on the sliding window, select the appropriate window width of one-dimensional curve smoothing and noise reduction, according to the frequency of the desired signal.)

说明：  问题的提出：根据“心”形曲线的数学参数方程，绘制曲线并输出屏幕。在各坐标点处循环显示“LOVE”的各字母。 编程思路：“心”形曲线的数学参数方程为: (Of the problem: According to the &quot heart&quot -shaped mathematical curve parameter equation, drawing curves and output screen. Coordinates of points in the cycle show &quot LOVE&quot in the letter. Programming idea: &quot heart&quot -shaped mathematical curve parameter equation:)

一个简单的画图程序，适合了解和学习C++画图，(a simple draw program)

VB编写的画图板，使用方便可以帮助代码学习。。(VB prepared the drawing board, easy to use can help the code to learn. .)

说明：  多重分形去趋势来分析处理生物医学信号，matlab程序代码(Multifractal detrended)

PSCAD Case for generator

在AutoCAD中添加一个自定义分页侧边栏。(In AutoCAD add a custom tab sidebar.)

说明：  常用光瞳函数，矩形函数、圆域函数、正六边形函数、三角形函数的绘制(Commonly used pupil function, including rectangle function, circle function, hexagon function, triangle function)
