你可以直接在MATLAB里面輸入指令，也可以把你所有需要的指令寫在一個(gè)m文件里面，然后再運(yùn)行文件。如果你把所有的m文件都放入啟動(dòng)MATLAB的目錄里面，那么MATLAB就能一直找到它們。 MATLAB提供了相當(dāng)豐富的幫助信息，同時(shí)也提供了獲得幫助的方法。 首先，可以通過桌面平臺(tái)的【Help】菜單來獲得幫助，也可以通過工具欄的幫助選項(xiàng)獲得幫助。此外，MATLAB也提供了在命令窗口中的獲得幫助的多種方法，在命令窗口中獲得MATLAB幫助的命令及說明列于表3-1中。其調(diào)用格式為： 命令+指定參數(shù) 表3-1 命 令 說 明 doc 在幫助瀏覽器中顯示指定函數(shù)的參考信息 help 在命令窗口中顯示指定命令M文件幫助 helpbrowser 打開幫助瀏覽器，無參數(shù) helpwin 打開幫助瀏覽器，并且見初始界面置于MATLAB函數(shù)的M文件幫助信息 lookfor 在命令窗口中顯示具有指定參數(shù)特征函數(shù)的M文件幫助 web 顯示指定的網(wǎng)絡(luò)頁(yè)面，默認(rèn)為MATLAB幫助瀏覽器 例如： >>help sin SIN Sine SIN(X) is the sine of the elements of X Overloaded methods Help sym/sin.m 另外也可以通過在組件平臺(tái)中調(diào)用演示模型（demo）來獲得特殊幫助。 在MATLAB中使用幫助指令 MATLAB具有相當(dāng)不錯(cuò)的聯(lián)機(jī)幫助，輸入： help commandname 要想得到給定指令的更多信息，你需要知道你要搜索的指令的名稱，本教程中使用的所有指令都在羅列在指令清單里面，這個(gè)頁(yè)面的鏈接可以在本頁(yè)面的右上角找到。 B B = 另外,你可能已經(jīng)注意到,只要你不給變量分配一個(gè)特定的操作或結(jié)果,MATLAB會(huì)把它存儲(chǔ)在一個(gè)名為ans的臨時(shí)變量里面。 想搞清楚你安裝的版本和那些工具箱嗎？使用ver試試： >> ver ------------------------------------------------------------------------------------- MATLAB Version 7.1.0.246 (R14) Service Pack 3 MATLAB License Number: 161051 Operating System: Microsoft Windows 2000 Version 6.0 (Build 6002: Service Pack 2) Java VM Version: Java 1.5.0 with Sun Microsystems Inc.
