【摘要】 针对《数值分析》课程中傅里叶变换知识抽象度高、难于理解的特点,利用MATLAB强大的计算功能,结合傅里叶变换中的具体算法,实现了课堂教学中的各种运算、绘图的直观演示,加深学生对算法的理解,并且能够运用MATLAB自带的函数fft()函数解决实际问题,极大地提高了教学效果.更多还原

【Abstract】 According to the characteristics of high abstraction and difficult to understand of the Fourier transform knowledge in the " numerical analysis" course,we use the powerful function of MATLAB,combined with the algorithm of Fourier transform,achieved the demonstrations of various operation and drawing in classroom teaching,and deepen the students’ understanding of the algorithm,and therefore we can use the built- in MATLAB function FFT() function to solve practical problems,and we can greatly improve the teaching effect.更多还原
