2.调试功能M程序调试器的热键设置和VC的设置有些类似,如果用户有其他语言的编程调试经验,则调试M程序会显得相当简单 不过M程序可能会经常出现索引错误,如果设置了stop if error(如果出错则停止,在Breakpoints菜单下),则程序的执行会停在出错的位置,并在MATLAB命令行窗口显示出错信息。下面列出了一些常用的调试方法。(1...
function [ out ] = w1(r, h) if nargin==1 h = 1; end if 0<=r && r<h q = r/(h/2); theta = 10/(7*pi*h^2); if q<=1 out = theta* (1-1.5*q^2+0.75*q^3); else out = theta* (0.25*(2-q)^3); end else out = 0; end end % file: w2.m function [ out ]...
Also, Ctrl+C might be less responsive if you start MATLAB with the -nodesktop option. Note For certain operations, stopping the program might generate errors in the Command Window. To programmatically stop execution of a function or script before reaching the end, use the return function. ...

In MATLAB, you must specify start and stop if you want to specify either of them. Thus, Python does not have the end keyword, since you can omit stop to achieve the same behavior. Try out the following examples of the slice syntax in NumPy: Python In [1]: import numpy as np In ...
Your code will execute more quickly if it is implemented in a function rather than a script. Every time a script is used in MATLAB, it is loaded into memory and uated one line at a time. Functions, on the other hand, are compiled into pseudo-code and loaded into memory once. Therefor...
