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:)

mfc 实现绘制3次B样条 效果很好 模块化可以在自己论文中使用(mfc achieved drawing cubic B-spline)

MATLAB下绘制三维极坐标图，输入极径和角度范围，还可以选择画图的种类，也可以画等高线图(Draw three-dimensional polar plot using MATLAB.)

此文件是用来计算电源buck 拓扑 的 MATHCAD 计算文件。(This file is used to calculate the Power buck topology MATHCAD calculation file.)

图形学上机实验，用三种算法画线。包括Bresenham画线算法、中点画线和数值微分画线算法(Graphics on an experiment with three algorithms draw the line. Bresenham line algorithm, the dotted line and numerical differential line drawing algorithm)

pscad搭建的ieee34节点配网模型，含风电和光伏(IEEE34 distribution grid with Wind and PV )

联合对角化方法,用于对多个矩阵同时进行联合对角化,主要用处是盲源分离,(Joint diagonalization method, is used to conduct joint diagonalization matrix at the same time for multiple, main use is to blind source separation,)

信号频谱分析 1. 观测已知方波信号、正弦波信号的频谱 分析频率为4KHz、8KHz的占空比为50 的方波信号、正弦波信号的频谱。记录所得频谱图。 观测实时模拟信号（语音）的频谱 用音频设备采集一段语音，将语音存为.wav格式。对wav文件作分段傅里叶变换分析。语音是分音节的，应把它分段分析，而且实际运用中的数字信号处理的FFT的点数是有限的，一般只能达到千点。用傅里叶反变换IFFT，从频域恢复信号。画出频谱图和语音波形图(Signal spectrum analysis 1. Observing a known square-wave signal, sine wave signal frequency spectrum analysis 4KHz, 8KHz for the 50 duty cycle square wave signal, sine wave signal frequency spectrum. The recorded frequency spectrum. Observing real-time analog signal (voice) of the spectrum collected with the audio devices section of voice, voice saved as. Wav format. Wav file of the sub-Fourier transform analysis to make. Speech is divided into syllables, it should be sub-analysis, and practical application of digital signal processing of the FFT points is limited, generally only reach 1000 points. Fourier inverse transform IFFT, to restore the signal from the frequency domain. Draw maps and voice waveform spectrum)
