Could you please rectify the error in the following program

To find the redundant feasibility matrix

clc
i=input ('enter the no.of constriants');
j=input( 'enter the no.of variables');
k=i;
for m=1:i
  for n=1:j
      if p=m-k
          F= a(m,n)-[b(m,:)*a(k,n)/b(k,:)];
      else
          disp(F=0)
      end
      l=fminbnd symsum(subminus F(m,n),m;[1,i];n;[1,j));
      for p=m-l
          if l=fminbnd
              assignin('base',lambda(l,:)=1);
          else
              assignin('base',lambda(i,:)=0);
          end
      end
      assignin('base',p=m-l);
      min(symsum subminus[lambda(l,:)*F(l,n)+symsum(lambda*F(m,n),m[1,i] n,[1,j]]);
      if lambda(l,:)*F(l,n)>=0
          lambda*F(i,j)+lambda(l,:)*F(l,j)>=0;
          lambda>=0;
      else
          disp('redundancy cannot be considered');
      end
      if
          lambda(m,:)*F(m,n)>=0;
          lambda(m,:)>=0
          lambda(m,:)>0
          disp('fval=0');
      disp('the kth constraint is redundant');
      else
          disp('the redundancy of the kth constraint cannot be determined');
      end
  end
end

If I run the program I get the error as Error: File: algorithm.m Line: 7 Column: 13 The expression to the left of the equals sign is not a valid target for an assignment.

[priya nair]

am getting the error in

    l=fminbndsymsum(subminus F(m,n);m;[1,i];n;[1,j]);

am getting error as Error: File: algorithm.m Line: 12 Column: 34 Unexpected MATLAB expression.

Line 7 is

if p=m-k

You probably do not want to assign (=), but compare (==, ~=, etc)
