Need help in MATLAB. Urgent Please. I got error in the last two statement. How to solve it? Thanks.

You need to: - Read in the entire Excel workbook (there is only one worksheeet and do not specify any cell range). Save the text data in GradesTxt and the numeric data in GradesDat Calculate the final grade for the students. The grade distribution is the homework is worth 20% of the final grade, and each exam is worth 40%. Store the vector of all the final grades in the variable Final .Compute the average final grade and store it in AveGrade. .Find the maximum final grade and its position. Store them as MaxGrade and Maxlndex . Use the position stored in Maxlndex to find the name of the highest performing student and store it in MaxStudent. . Create an output message (using sprintf) and store it in the character array Results. The message should match the following message exactly "The average grade was XX.X with a maximum score of YY.Y by NNN." Where XX.X is the average grade, YY.Y is the maximum grade, and NN is the name of the student who made the maximum score. 1 %% Variables to be used 2 % Inputs 3 % CU3 141-G rades.xlsx is a spreadsheet as described in the problem statement 4 5 % Intermediate 6 % GradesTxt-cell array containing all the text data from the Excel sheet 7 % GradesDat-matrix containing all the numeric data from the Excel sheet 9 % Outputs 10 % Final-vector of all final grades 11 % AveGrade-average of all final grades 12 % MaxGrade -maximum of all final grades 13 % Maxindex- position of MaxGrade in Final vector 14 % Maxstudent - name of student who earned the maximum grade 15 % Results-character array containing formatted output statement 16 17 %% Inputs -Only edit this section if you are testing this code in MATLAB 18 % There are no inputs for this problem other than the Excel file which you will have to read in. 19 % You wil need to create your own copy of the Excel file to use when you run this code in MATLAB. 20 21 %% PROGRAM 22 % Start writing your program here 23 [GradesDat GradesTxt]-xlsread ( 'CU3141_Grades.xlsx'); 24 Homework-(GradesDat(1:end,1)*20)/100; 25 Exam1-(GradesDat (1:end,2)*40)/100; 26 Exam2-(GradesDat (1:end, 3)*40)/100; 27 Final-Homework+Exam1+Exam2; 28 AveGrade-mean (Final); 29 [MaxGrade MaxIndex]-max (Final(:)); 30 MaxStudent-GradesTxt (MaxIndex(1,: )) 31 Results-fprintf('The average grade was %0.2f% with a maximum score of %0.2f% by %s .AveG rade,MaxGrade,Ma 32 3 MaxStudent Check Variable MaxStudent has an incorrect value If you got the previous test correct (Maxlndex) then you need to check your row and column indexing.
