can anyone please help me in rectifying the error

on executing the following code am getting the error

      clc
  i = input ('enter the no. of constraints: ');
  j= input ('enter the no. of variables: ');
  for m=1:i
      for n=1:j
          d(m,n)= a(m,n)/b(m)*c(n);
          max(min(d(m,n)))= min(max(d(m,n)));
          disp('no redundant constraints');   
  le(d(k,n),d(m,n));
  disp('the kth constraint is  redundant');
          end
      end

am getting the error as Undefined function 'a' for input arguments of type 'double'.

Error in stain (line 6) d(m,n)= a(m,n)/b(m)*c(n);

please help me in rectifying the error

You have to have a matrix called ‘a’ (and vectors ‘b’ and ‘c’) existing in your workspace before you run the code you posted.

To be honest, the code you posted does not make sense.
