四川师范大学MATLAB语言实验报告1系级班年月日实验名称：Intro, Expressions, Commands姓名学号指导教师成绩1ObjectiveThe objective of this lab is to familiarize you with the MATLAB program development environment and to develop your first programs in this environment.2Using MATLAB2.1Starting MATLABLogon to your computer and start MATLAB by double-clicking on the icon on the desktop or by using the Start Programs menu. MATLAB Desktop window will appear on the screen.The desktop consists of several sub-windows. The most important ones are:●Command Window (on the right side of the Desktop) is used to do calculations,enter variables and run built-in and your own functions.●Workspace (on the upper left side) consists of the set of variables (arrays) createdduring the current MATLAB session and stored in memory.●Command History (on the lower left side) logs commands entered in theCommand Window. You can use this window to view previously run statements, and copy and execute selected statements.You can switch between the Launch Pad window and the Workspace window using the menu tabs under the sub-window on the upper left side. Similarly, you can switch between the Command History and Current Directory windows using the menu tabs under the sub-window on the lower left side.2.2Executing CommandsYou can type MATLAB commands at the command prompt “>>” on the Command Window.For example, you can type the formula cos(π/6)2sin(3π/8) as>>(cos(pi/6) ^ 2) * (sin(3 * pi/8))Try this command. After you finish typing, press enter. The command will be interpreted and the result will be displayed on the Command Window.Try the following by observing how the Workspace window changes:>> a = 2; (M ake note of the usage of “;”)>> b = 3;>> c = a ^ 4 ∗ b ∗ 5 + pi ^3You can see the variables a, b and c with their types and sizes on the Workspacewindow, and can see the commands on the Command History window.Spend a few minutes to practice defining array variables (i.e. vectors and matrices)usingthe square bracket (“[ ]”) and colon (“:”) operators, and zeros() and ones() functions.>> ar =[ 1 2 3 4 5 ];>> br =[ 1 2 3 ;4 5 6 ];>> cr = [1 : 3 : 15];• Set dr to first 3 elements of ar.dr=ar(1:3);• Set er to second row of br.er=br(2,:);• Set ar to [dr er]. Find the number of elements of ar.ar=[dr er]; length(ar)2.3 Getting HelpThere are several ways to get help on commands and functions in MATLAB. First ofall you can use the Help menu. You can also use the “?” button. Try to findinformation on the plot function from the help index. Also try to get information onthe same function using the help command (i.e. type help plot). Finally, experimentwith the lookfor command. This command looks for other commands related to agiven keyword.2.4 Some Useful CommandsTry the following commands and observe their results:Which : Version and location infoClear : Clears the workspaceClc : Clears the command windowwho, whos : Lists content of the workspace3 ExercisesPlease solve the following problems in MATLAB. Do not forget to keep a diary ofyour commands and their outputs.(1) Define the variables x y and z as 7.6, 5.5 and 8.1, respective ly, and evaluate:578.422.52⎪⎭⎫ ⎝⎛-x y xz(2) Compute the slope of the line that passes through the points (1,-2) and(5,8).(3) Quiz 1.1: 5(4)1.6 Exercises: 1.1, 1.4(5)2.15 Exercises: 2.6, 2.9, 2.114Quitting MATLABTyping quit on the command window will close the program. Do not forget to send your diary file and M-file to your TA.Do not forget to delete your files from the hard disk of the PC you used in the lab at the end of the lab session.四川师范大学MATLAB语言实验报告2系级班年月日实验名称：Programming, Relational and Logical Expressions姓名学号指导教师成绩1ObjectiveThe objective of this lab is to familiarize you with the MATLAB script files (M-files), subarrays, relational and logical operators.2Script FilesScript files are collections of MATLAB statements that are stored in a file. Instead of typing commands directly in the Command Window, a series of commands may be placed into a file and the entire file may be executed by typing its name in the Command Window. Such files are called script files that are also known as M-files because they have an extension of .m. When a script file is executed, the result is the same as it would be if all of the commands had been typed directly into the Command Window. All commands and script files executed in the Command Window share a common workspace, so they can all share variables in the workspace. Note that if two script files are executed successively, the second script file can use the variables created by the first script file. In this way, script files can communicate with other script files through the data left behind in the workspace. An Edit Window is used to create new M-files or to modify existing ones. The Edit Window is a programming text editor, with the features of MATLAB language highlighted in different colors. You can create a new M-file with the File/New/M-file selection and you can open an existing M-file with the File/Open selection from the desktop menu of MATLAB. (1)Create a new working directory under the current directory and change the currentdirectory to ‘TA’s suggest’.3SubarraysIt is possible to select and use subsets of MATLAB arrays. To select a subset of an array, just include a list of the elements to be selected in the parentheses after the array name. MATLAB has a special function named end that is used to create arraysubscripts. The end function always returns the highest value taken on by a givensubscript. It is also possible to use subarrays on the left-hand side of an assignmentstatement to change only some of the values in an array. If values are assigned to asubarray, only those values are changed but if values are assigned to an array, theentire contents of the array are replaced by the new values.(1) Define the following 5 x 5 array arr1 in MATLAB.⎥⎥⎥⎥⎥⎥⎦⎤⎢⎢⎢⎢⎢⎢⎣⎡----=2274235421209518171651413215111012844563311arr(2) Write a MATLAB statement to select a subset of arr1 and return the subarraycontaining the values as shown.⎥⎦⎤⎢⎣⎡=22745456311arrarr11=arr1([1,5],[2 4 5]);(3) Write two MATLAB statements to select the last row and last column of arr1,separately.arr12=arr1(5,:);或arr12=arr1(end,:); arr13=arr1(:,end);或 arr13=arr1(:,5);(4) Write MATLAB statements to obtain the following array from arr1.⎥⎥⎥⎥⎥⎥⎦⎤⎢⎢⎢⎢⎢⎢⎣⎡-=2257462335432112arrarr2=arr1([1 5],:)';4 Relational and Logical OperatorsRelational and logical operators are the two types of operators that produce true/falseresults in MATLAB programs. MATLAB interprets a zero value as false and anynonzero value as true. Relational operators ( ==, =,>,>=,<,<=) are operators with twooperands that produce either a true (1) or a false (0) result, depending on the values ofthe operands. Relational operators can be used to compare a scalar value with an array.They can also be used to compare two arrays or two strings only if they have the samesize. Be careful not to confuse the equivalence relational operator ( == ) with theassignment operator ( = ). Logic operators ( &, |, xor, ～ ) are operators with one ortwo operands that yield a logical result such as 0 or 1. There are three binary logicoperators: AND (& ), OR ( |), and exclusive OR ( xor ); and one unary operator: NOT( ～ ). In the hierarchy of operations, logic operators are evaluated after allarithmetic and relational operators have been evaluated. The operator is evaluatedbefore other logic operators.(1) Define the following 4 x 5 array arr4 in MATLAB.⎥⎥⎥⎥⎦⎤⎢⎢⎢⎢⎣⎡------=212343212343212543214arr(2) Write an expression using arr4 and a relational operator to produce the followingresult.⎥⎥⎥⎥⎦⎤⎢⎢⎢⎢⎣⎡=110001110011110111115arrarr5=arr4>0;(3) Write an expression using arr4 and a relational operator to produce the followingresult.⎥⎥⎥⎥⎦⎤⎢⎢⎢⎢⎣⎡=010000010000010000016arrarr6=arr4==1;(4) Write a MATLAB program which will generate an (n-1)x(n-1) matrix from agiven nxn matrix which will be equal to given matrix with first row and firstcolumn deleted.arr44=rand(5); arr444=arr35(2:end,2:end);(5) Generalize your program above so that the program should ask the row andcolumn numbers to be deleted and then generate new (n-1)x(n-1) matrix.n=input('input n:');matrixn=rand(n)delrow=input('input row numbers to be deleted:');delcolumn=input('input column numbers to be deleted:');matrixn_1=matrixn([1:delrow-1 delrow+1:end], [1:delcolumn-1 delcolumn+1:end])(6) Quiz 3.1 （P88）5 Quitting MATLABTyping quit on the command window will close the program.
