打印机控制,C++的动态库,编译过,好用(print control)

永磁同步电机和直流电机调速，simulink仿真，看看大家有没有用(Permanent magnet synchronous motor and DC motor speed)

多目标决策方法之一的ELECTRE的重要实现代码。 (ELECTRE MATLAB Code)

说明：  这是基于STM32和FPGA的简易数字存储示波器(This is Simple Digital Storage Oscilloscope Based on STM32 and FPGA)

浙江大学ａｃｍ试题答案之１００２，此题目比较ｅａｓｙ,可能有不足之处，望指教(Zhejiang University acm answer questions of 1002, comparing the subject easy, may have deficiencies, Point index)

基于ArcEngine的三维GIS演示系统，利用ArcScene开发的三维GIS漫游系统(Three-dimensional GIS-based presentation systems ArcEngine, the use of three-dimensional GIS ArcScene Roaming System Development)

C# 读取MP3歌曲文件标志信息并使用Quartz库播放、读取WAV歌曲文件标志信息、使用Quartz库播放MP3歌曲、使用Quartz库播放DVD视频、弹出光驱、关闭光驱等功能，获取的MP3文件信息包括歌名、艺术家、签名册、发行日期等。同时还可以读取WAV歌曲文件标志信息，具体的标记信息请下载本源码查看Form1.cs文件。本实例部分功能需要依赖Interop.QuartzTypeLib.dll组件来实现。

用C语言实现的离散傅里叶变换（DFT）的经典算法！比较实用！(C language classic of the discrete Fourier transform (DFT) algorithm! More practical!)

1、 极大似然估计 尝试用0~24阶多项式拟合，并用5折交叉验证选择最佳模型（多项式阶数及其系数，给出类似课件中的图），并画出最佳模型的拟合效果图（类似图1，蓝色点为训练样本、红色点为测试样本、绿色线为模型预测），给出该模型的测试误差。 2、 岭回归 多项式阶数为24，正则系数λ的取值范围为exp(-19)到exp(20)，采用并用5折交叉验证选择最佳模型。实验结果要求同1。 (1, the maximum likelihood estimate of 0 to 24 try-order polynomial fitting, with 5-fold cross-validation to select the best model (polynomial order and coefficients are given in Figure similar courseware), and draw the best model Fitting renderings (similar to Figure 1, a blue dot to the training sample, the test sample is red dot, the green line is the model prediction), the test error of the model are given. 2, ridge regression polynomial order of 24, the regular coefficient ranges λ is exp (-19) to exp (20), and with the use of 5-fold cross-validation to select the best model. The experimental results with a requirement.)
