在本资源中,我们预期将包含两个主要部分:使用Python语言编写的线性代数相关代码,以及使用MATLAB语言编写的对应线性代数实现。这些代码将支持在线课程的学习,为学生提供实践操作的机会,以加深对线性代数概念的理解。 ### Python线性代数代码知识点: 1. **NumPy库的使用**:Python中的NumPy库是处理线性代数问题的基础,包括但不限于矩阵运算、向量运算、特征值与特征向量计算等。这部分内容将详细介绍如何使用NumPy进行科学计算。 2. **矩阵运算**:包括矩阵的加法、减法、乘法以及转置等基础操作。在课程中,将通过编写Python代码来演示如何实现这些操作。 3. **线性方程组求解**:讨论如何用Python求解线性方程组,这可能包括使用NumPy的`linalg.solve`函数。 4. **特征值和特征向量**:对于理解线性变换和矩阵的性质至关重要,课程内容将涉及如何利用Python计算矩阵的特征值和特征向量。 5. **矩阵分解**:如LU分解、QR分解等,这些是解决线性系统和优化问题的常用方法,相关的Python实现将在课程中进行介绍。 6. **向量空间和子空间**:通过Python代码演示如何创建和操作向量空间,包括基和维度的概念。 7. **线性变换**:包括线性变换的表示、如何使用矩阵进行线性变换等。 ### MATLAB线性代数代码知识点: 1. **MATLAB基础**:对MATLAB环境进行基础介绍,包括矩阵和数组操作,命令窗口使用等。 2. **矩阵运算**:在MATLAB中进行矩阵和向量的基本操作,如何通过内置函数快速完成矩阵运算。 3. **线性方程组求解**:MATLAB提供了多种求解线性方程组的方法,包括直接法和迭代法。课程将介绍如何运用这些方法。 4. **特征值和特征向量**:利用MATLAB内置函数进行特征值和特征向量的计算。 5. **矩阵分解**:演示LU分解、QR分解等矩阵分解技术在MATLAB中的实现和应用。 6. **多维数组操作**:MATLAB在处理多维数据上具有优势,这部分将涉及多维数组的创建、操作和应用。 7. **图形化表示**:MATLAB强大的图形处理能力使它非常适合于教学,课程将展示如何利用MATLAB绘制向量、矩阵、线性变换的图像。 8. **编程结构**:介绍MATLAB的脚本、函数、循环和条件语句,以及如何利用这些编程结构来编写更复杂的算法。 ### 资源结构: - **LinAlgCourse-main文件夹**:包含所有主要的线性代数教学材料和相关代码。这部分内容可能被组织成不同的子文件夹,每个子文件夹对应课程的一个教学单元或主题。 - **新建文件夹**:可能用于存放课程学习的额外资源,例如补充材料、练习题、案例研究等。 通过本资源,学习者可以获得理论与实践相结合的学习体验,将抽象的数学概念转化为直观的代码实现,从而更深入地理解和掌握线性代数的各个方面。"

7-3 Score Processing 分数 10 作者 翁恺 单位 浙江大学 Write a program to process students score data. The input of your program has lines of text, in one of the two formats: Student's name and student id, as <student id>, <name>, and Score for one student of one course, as <student id>, <course name>, <marks>. Example of the two formats are: 3190101234, Zhang San 3190101111, Linear Algebra, 89.5 Comma is used as the seperator of each field, and will never be in any of the fields. Notice that there are more than one word for name of the person and name of the course. To make your code easier, the score can be treated as double. The number of the students and the number of the courses are not known at the beginning. The number of lines are not known at the beginning either. The lines of different format appear in no order. One student may not get enrolled in every course. Your program should read every line in and print out a table of summary in .csv format. The first line of the output is the table head, consists fields like this: student id, name, <course name 1>, <course name 2>, ..., average where the course names are all the courses read, in alphabet order. There should be one space after each comma. Then each line of the output is data for one student, in the ascended order of their student id, with score of each course, like: 3190101234, Zhang San, 85.0, , 89.5, , , 87.3 For the course that hasn't been enrolled, leave a blank before the comma, and should not get included in the average. The average has one decimal place. There should be one space after each comma. And the last line of the output is a summary line for average score of every course, like: , , 76.2, 87.4, , , 76.8 All the number output, including the averages have one decimal place. Input Format As described in the text above. Output Format As described in the text above. The standard output is generated by a program compiled by gcc, that the round of the first decimal place is in the "gcc way". Sample Input 3180111435, Operating System, 34.5 3180111430, Linear Algebra, 80 3180111435, Jessie Zhao 3180111430, Zhiwen Yang 3180111430, Computer Architecture, 46.5 3180111434, Linear Algebra, 61.5 3180111434, Anna Teng Sample Output student id, name, Computer Architecture, Linear Algebra, Operating System, average 3180111430, Zhiwen Yang, 46.5, 80.0, , 63.2 3180111434, Anna Teng, , 61.5, , 61.5 3180111435, Jessie Zhao, , , 34.5, 34.5 , , 46.5, 70.8, 34.
