Question

Write a user-defined function that sorts the elements of a matrix. For the function name and arguments use B = matrixsort(A), where A is any size matrix and B is a matrix of the same size with the elements of A rearranged in descending order row after row with the (1,1) element the largest and the (m, n) element the smallest. Test your function on a 4 x 7 matrix with elements (integers) randomly  distributed between( -30 and 30). Use MATLAB's randi function to generate the initial matrix.

please try to solve this problem by converting the matrix to a vector using the a sort functiion then reconverting it back to a matrix , please comment your steps in the code so i can understand your logic thanks.

Explanation / Answer

% required function

function B = matrixsort(A)

% getting rows and columns of A

[r,c]=size(A);

% converting A to vector

vec = A(:);

% sorting vector in descending order

vec = sort(vec,1,'descend');

% reshaping vector back to original matrix dimensions

B = reshape(vec,c,r)';

end

% end of function

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

% TESTING above function

% creating 4 x 7 random matrix

A = randi([-30,30],4,7);

% sorting matrix

B = matrixsort(A);

% displaying result

disp('Sorted matrix is:');

disp(B);
