Matlab軟件介紹
Matlab software introduction
Matlab和Mathematica、Maple并稱為三大數(shù)學軟件。它在數(shù)學類科技應用軟件中在數(shù)值計算方面首屈一指。行矩陣運算、繪制函數(shù)和數(shù)據(jù)、實現(xiàn)算法、創(chuàng)建用戶界面、連接其他編程語言的程序等。MATLAB的基本數(shù)據(jù)單位是矩陣，它的指令表達式與數(shù)學、工程中常用的形式十分相似，故用MATLAB來解算問題要比用C，F(xiàn)ORTRAN等語言完成相同的事情簡捷得多，并且MATLAB也吸收了像Maple等軟件的優(yōu)點，使MATLAB成為一個強大的數(shù)學軟件。在新的版本中也加入了對C，F(xiàn)ORTRAN，C ，JAVA的支持。
Matlab, Mathematica, and Maple are collectively called the three major mathematical software. It is second to none in numerical calculation in mathematical science and technology application software. Row matrix operations, drawing functions and data, implementing algorithms, creating user interfaces, connecting programs in other programming languages, etc. The basic data unit of MATLAB is a m百思特網(wǎng)atrix. Its instruction expressions are very similar to those commonly used in mathematics and engineering. Therefore, it is much simpler to use MATLAB to solve problems than to use C, FORTRAN and other languages to accomplish the same thing, and MATLAB also Absorbed the advantages of software like Maple, making MATLAB a powerful mathematical software. In the new version, support for C, FORTRAN, C , and JAVA has also been added.
Matlab界面介紹
Matlab interface introduction
1.軟件下載完畢后點擊“預設(shè)”——“字體”更改自己需要的頁面設(shè)置。
2.主頁中點擊“新建”——“腳本” 。新建的腳本就是當前需要編輯的地方。
3.編輯完成之后按“Ctrl S”進行保存。
4.清除命令行窗口內(nèi)容，填寫“CLC”即可清除工作區(qū)內(nèi)容，在命令行窗口填寫“clear all” 。
1. After the software is downloaded, click “Preset”-“Font” to change the page settings you need.
2. Click “New”-“Script” on the homepage. The newly created script is the place that needs to be edited currently.
3. After editing, press “Ctrl S” to save.
4. To clear the contents of the command line window, fill in “CLC”, clear the contents of the work area, and fill in “clear all” in the command line window.
Matlab數(shù)據(jù)類型
Matlab data type
1.字符與字符串
1.Characters and strings
S=’a’ ’ ’中間所表示的所有內(nèi)容即為字符串
Abs(s) 表示為每個字符都有其對應的ASCII值
Char( ) 表示字符串
Num2str(65) 表示為數(shù)字65轉(zhuǎn)換成為’65’
Length(str) 表示為字符串長度
S=’a’ ’ ’indicates everything in the middle is a string
Abs(s) means that each character has its corresponding ASCII value
Char() represents a string
Num2str(65) is expressed as the number 65 converted into ’65’
Length(str) is expressed as the length of the string [the length includes the space bar]
2.矩陣
Matrix
可用A=[1 2 3;4 5 2;3 2 7]舉例
Available A=[1 2 3;4 5 2;3 2 7] example
B=A’ 表示矩陣行列將互相變換
B=A’ matrix rows and columns will be transformed into each other
C=A: 表示矩陣將豎拉一排
C=A: The matrix will be drawn vertically in one row [starting from the first column]
D=inv(A) 表示矩陣求逆
E=zeros(10,5,3) 表示生成十行五列且為三位
的0矩陣命令行窗口中E=(:,:,1)即表示一維矩陣
E=(:,:,1)=rand(10,5)
