简单地说,tic和toc是用来记录matlab命令执行的时间 tic用来保存当前时间,而后使用toc来记录程序完成时间. 两者往往结合使用,用法如下: tic operations toc 显示时间单位: 秒 Tic和toc函数可以计算运行一段时间的代码 例如: clc tic d=zeros(1,10000); for i=1:10000 d(i)=i; end toc tic c=1; for i=1:10000 c=[c:i]; end toc 运行结果如下: Elapsed time i
Tic和toc函数可以计算运行一段时间的代码. 例如: clc tic d=zeros(1,10000); for i=1:10000 d(i)=i; end toc tic c=1; for i=1:10000 c=[c:i]; end toc 运行结果如下: Elapsed time is 0.000158 seconds. Elapsed time is 0.152307 seconds. 只要用tic和toc函数,不需要自己计算前后时间的差,tic函数会记录起始时刻,toc函数会自动计算
很多海外留学生在Essay写作时往往不善于对单词进行变化,不能将同一个意思用不同的方式表达出来,使得Essay显得单调乏味最终拿不到高分.小编建议大家应该尽量减少Essay写作中的重复用词.本文将为大家介绍这几种方法减少重复用词,实现用词多样化: 方法一:同义词替换 这是最简单的一种替换方法,当句子或段落中一个词出现太多次时,我们可以用单词的同义词来替换.举两个<经济学人>的例子: Just as drones can make up for poor roads,the theory goe

tic Start a stopwatch timer. tic and TOC functions work together to measure elapsed time. tic, by itself, saves the current time that TOC uses later to measure the time elapsed between the two. TSTART = tic saves the time to an output argum
