ENGR 101 Lab # 5 Cell Arrays and Data Visualization interesting picture related to the lab here perhaps something related to one of the exercises needs to be related to engineering

Lab 5: Cell Arrays and Data Visualization Due Saturday, 2/12, 2022 at 11:59PM EDT on Gradescope. NO EXCEPTIONS! Your lab MUST be submitted to Gradescope by the deadline or you will not receive credit! This lab is worth 40 points and is graded for completion. However, earning a grade depends on attendance and participating during the lab. Your lab instructor will record the attendance for each lab. Our team name is...

Lab 5: Cell Arrays, Excel Files, Data Visualization MATLAB has a huge variety of ways to visualize data. It’s a platform which is well designed to both read, store, and display data which makes it excellent for many engineering applications. You don't need to memorize all of these visualization functions - MATLAB provides good documentation for you to reference. Each member of your team should open up the documentation ( link ) and list one of the plots that MATLAB supports in the box below. Put N/A if you don't have a person D and/or E. This lab has less instructions than others because we want you to use the Mathworks documentation extensively when plotting. One helpful way to open documentation (when you already know a function’s name) is typing the following command into the command window: EhBelp Cfun@ctFion°>amBe Have your coder type: EhBelp su?bplot >anAd EhBelp @comBet3 into the command window and see what pops up in the command window. These two functions will aid you later on during the lab. This even works for functions which you’ve written (not built in) provided that you’re in the correct folder.

Exercise 1: Cell Array Practice (20 mins) The *aTTUVWJWWX should share their screen and launch MATLAB. Create a cell array named @cBelBery with the following values: Write the MATLAB expression used to build this cell array: Type, and Size of Result: celery = {2.06, [17 22 21 5]; 'hi' , 'A' }; 2x2 ±!ll ‘hi’ 2.06 17 22 21 5 ‘A’

Exercise 1: Cell Array Practice For the cell array created, what would the return value, type, and size be for the following MATLAB expressions? Discussion Leader MATLAB expression Value, Type, and Size of Result Person A ´ = @cBelBery{1,2} 1 x 4, double Person B ´ = @cBelBery(1,1) 1 x 1 cell Person C ´ = @cBelBery{1,:} 1 x 1 double Person D ´ = @cBell2m>at(@cBelBery(1,:)) 1 x 5 double The *aTTUVWJWWX should share their screen and launch MATLAB. For each of the following expressions, make a prediction of the value of the variable first and then double check by trying it out in MATLAB. Each has a different discussion leader. The :EUWWX[NTWJ records and the 8ZZ[WJXXYYYZ[NaTTU`SSWJWWX tracks any questions the .aTTUaTTUYL^QQWJWWX is unable to find an answer to.

Exercise 1: Cell Array Practice Continue working with the @cBelBery cell array. For the following exercise, each discussion leader should write code for the desired operation on their own. If your letter isn’t included, pick one to do. The group should reconvene to discuss each operation. The :EUWWX[NTWJ records and the 8ZZ[WJXXYYYZ[NaTTU`SSWJWWX tracks any questions the .aTTUaTTUYL^QQWJWWX is unable to find an answer to. Write code to perform each of the following operations on the cell array @cBelBery : Discussion Leader Desired Operation MATLAB Code Person E Replace the value 2.06 with the value 4.06. @cBelBery{1,1} = 4.06; Person A Replace the value 17 with the value 15. celery{1,2}(1) = 15; Person B Create a new matrix called ²ro±±oli that is the same as ±!l!ry , but has an extra 3rd column that is a duplicate of the 1st column. broccoli = {celery{1, :}, celery{1,1}; celery{2,:}, celery{2,1}}; Person C Swap the strings 'hi' and ‘³’ in the cell array with a single line of code. celery(2, 1:1:2) = celery(2, 2:-1:1); # of mins this exercise took our team: 15
