28) Give an example to illustrate the difference between the linspace function and the colon operator. 29) A = [2; 7; 4] write this Matlab command in a different way. 30) Create a 4 by 3 matrix W and fill it with the following values M = 12 71 44 1 5 65 6 5 4 2 5 62 31) Create a 4 by 3 matrix R and fill it with the following values M = 3 2 43 11 4 65 21 65 7 21 23 9

1. Display Function Implement a function to display the contents of the patient_list array.  Add code to call this function. Note that there are multiple places where this function needs to be called. Look for the  // TODO comments to find the correct locations. Compile and test your program. Make sure that your output is formatted similarly to the sample output shown at the end of this document. The sorting part does not need to work yet.   Take a screenshot of a sample output and upload the picture as part of your assignment submission.   2. Sorting the array by Age   Implement the code to sort the contents of the patient_list array based on the value stored in the age field. To do this you will need to implement code that relies on the qsort function from the C Standard library(see http://www.cplusplus.com/reference/cstdlib/qsort/). As shown in the reference, this code requires two parts: A function that compares two patient elements, based on the value stored in the age…

. Load the file thermo scores.dat and name it thermo scores.(a) Extract the scores and student number for student 5 into a row vectornamed student 5.(b) Extract the scores for Test 1 into a column vector named test 1.(c) Find the standard deviation and variance for each test.(d) Assuming that each test was worth 100 points, find each student’s finaltotal score and final percentage. (Be careful not to add in the studentnumber.)(e) Create a table that includes the final percentages and the scores from theoriginal table.(f) Sort the matrix on the basis of the final percentage, from high to low (indescending order), keeping the data in each row together. (You may needto consult the help function to determine the proper syntax.)

1. Write MATLAB code to do each of the following. Include your answers in comments using %. a. Create an evenly spaced vector from 5 to 105 in increments of 5. b. Create a vector of 20 evenly spaced values from -2 to 2.
