matlab中有哪些有趣的命令?好玩的matlab彩蛋
生活随笔
收集整理的這篇文章主要介紹了
matlab中有哪些有趣的命令?好玩的matlab彩蛋
小編覺得挺不錯(cuò)的,現(xiàn)在分享給大家,幫大家做個(gè)參考.
比如說,我在command窗口輸入“xpbombs”然后回車運(yùn)行就會(huì)跳出一個(gè)掃雷游戲的小程序,或者輸入“vibes”運(yùn)行就會(huì)跳出一個(gè)膜振動(dòng)的動(dòng)畫,還可以調(diào)節(jié)快慢
嗯,就是這種的修改 舉報(bào)添加評論? 分享 ???邀請回答 按投票排序按時(shí)間排序

首先寫一個(gè)script,命名為startup.m
fprintf里面就是你想顯示的內(nèi)容啦,你寫hello world也好,keep calm and zhao lanxiang 也罷,都有一種調(diào)教自家Matlab的快感。
cd里是你的常用workspace directory
------------------------------------------
%startup.m
fprintf(1,'Hello! This is your beloved Queen MATLAB! \n');
fprintf(1,'Message form start.m\n\n');
fprintf(1,'I would like to torture you even more today-just kidding:)');
fprintf(1,'Reminder:when you add a new function to a tool box, issue command:\n');
fprintf(1,' rehash toolboxcache\n\n');
cd ('~/Documents/MyMath/project');
------------------------------------------
然后!把你存放這個(gè)腳本的路徑加入Matlab搜索路徑里!home-set path-add with subfolder!后生切記!
