图 1.8-1 1.9 Editor/Debugger 和脚本编写初步 1.9.1 Editor/Debugger M 文件编辑调试器简介一编辑调试器的开启二编辑器使用中的若干注意事项 1.9.2 M 脚本文件编写初步图 1.9-1 【例 1.9.2-1】编写解算例 1.3.4-1 题目的 M 脚本文件,并运行之。操作步骤: 1.10 帮助系统 1.10.1 帮助方式概述
一 “纯文本”帮助【例 1.10.1-1】在指令窗中运行 help 的示例。 (1) help help HELP On-line help, display text at command line. HELP, by itself, lists all primary help topics. Each primary topic corresponds to a directory name on the MATLABPATH. ...... ...... ...... (2) help HELP topics: matlab\general - General purpose commands. matlab\ops - Operators and special characters. matlab\lang - Programming language constructs. matlab\elmat - Elementary matrices and matrix manipulation. matlab\elfun - Elementary math functions. ...... ...... ...... For more help on directory/topic, type "help topic". (3) help elmat Elementary matrices and matrix manipulation. Elementary matrices. zeros - Zeros array. ones - Ones array. eye - Identity matrix. ...... ...... ...... (4) help eye EYE Identity matrix. EYE(N) is the N-by-N identity matrix. EYE(M,N) or EYE([M,N]) is an M-by-N matrix with 1's on the diagonal and zeros elsewhere. EYE(SIZE(A)) is the same size as A. See also ONES, ZEROS, RAND, RANDN. 【例 1.10.1-2】在指令窗中,运用 lookfor 找 H1 行(M 函数文件的第一注释行) lookfor fourier FFT Discrete Fourier transform. FFT2 Two-dimensional discrete Fourier Transform. FFTN N-dimensional discrete Fourier Transform. IFFT Inverse discrete Fourier transform. IFFT2 Two-dimensional inverse discrete Fourier transform. IFFTN N-dimensional inverse discrete Fourier transform. XFOURIER Graphics demo of Fourier series expansion. MOT563_FFT Discrete Fourier transform. MOT563_IFFT Inverse discrete Fourier transform. MOT566_FFT Discrete Fourier transform. MOT566_IFFT Inverse discrete Fourier transform. DFTMTX Discrete Fourier transform matrix. INSTDFFT Inverse non-standard 1-D fast Fourier transform. NSTDFFT Non-standard 1-D fast Fourier transform. FFT Quantized Fast Fourier Transform. FOURIER Fourier integral transform. IFOURIER Inverse Fourier integral transform.
