Is this correct?

(a) Write a MATLAB function matrixfn that takes values m and n as inputs and gives as output an m × n matrix A whose entries Aij are defined by Aij = i^2 + j^2

(b) Write MATLAB commands that use matrixfn to obtain the m × n matrix A for the following cases: (i) m = n = 5. (ii) m = 6, n = 9

THIS IS WHAT I HAVE DONE:

 function A= matrixfn(m,n)
for i=1:n
    for j=1:m
        A(i,j)=i^2 + j^2;
    end
end

Your output would be n x m instead of m x n

[Tawanda Le Bourne]

so it's i=1:m j=1:n

Answer 1

[KSSV]

   function A= matrixfn(m,n)
  A = zeros(m,n) ;
  for i=1:m
      for j=1:n
          A(i,j)=i^2 + j^2;
      end
  end

Save the above function in a folder. Go to that folder in MATLAB. And you can call it by:

A = matrixfun(2,2) ;
B = matrixfun(5,5) ;
C = matrixfun(6,9) ;
