Question

Write a code that gets the quiz grades of a class. A matrix with n rows and m columns where n stands for number of students and m is the number of quizzes. Let’s call the matrix A. Then, your code drops the lowest grade of each student and remove it from the matrix. Also, it finds the average grade for the quizzes for each student and add a new column to the end the matrix. in matlab please

Answer 1

SOLUTION:-

%MATLAB CODE:-

clear

n=input('enter no of students\n');

m=input('number of quiz');

for i=1:n

fprintf('enter grades of student %i\n',i);

for j=1:m

fprintf('quiz %i\n',j)

A(i,j)=input('enter grades');

end

end

fprintf('input matrix\n');

A

for i=1:n

B=A(i,:);

[~,a]=min(B);

B(a)=[];

C(i,:)=B;

end

fprintf('removed low grades\n')

A=reshape(C,n,m-1);

A

fprintf('final grade matrix after adding avg grades\n')

for i=1:n

A(i,m)=sum(A(i,:))/(m-1);

end

A

%end of MATLAB CODE
