说明：  可以识别电子文档,图片和手写的英文字母,用MatLAB打开即可(It can recognize electronic documents, pictures and handwritten English letters. It can be opened with MatLAB.)

以matlab为工具利用数字图像处理技术对答题卡进行了识别，并对识别结果进行了处理。注意到答题卡在采集图像的过程中由于各种原因可能会产生图像倾斜、水平或垂直错位，要进行正确识别首先必须对其进行校正，再依据像素检索技术进行识别。(With MATLAB as the tool, the answer card is identified by digital image processing technology, and the recognition results are processed. It is noted that the answer card in the process of collecting images may cause image tilt, horizontal or vertical dislocation for various reasons. To correct recognition, it is necessary to correct it first and then identify it according to the pixel retrieval technique.)

关于跳频信号的时频分析过程，介绍的比较详细(About the frequency hopping signal analysis process, described in more detail)

4Cyclist problem simulation model Four cyclists are at the desert. Each of them starts from a different location and tries to reach the other ones. Cyclist 1 goes straight to cyclist 2, cyclist 2 straight towards cyclist 3 etc. such that finally the cyclist 4 goes straight towards cyclist 1. Form the equations, build a Simulink-model and find out the meeting point of the cyclists by simulating the system with the following initial values:
