Remove NAN's from a matrix

i have the matrix: [5 4 3 2 1;Nan 4 3 2 1;Nan Nan 3 2 1] and i want to have [5 4 3 2 1; 4 3 2 1;3 2 1] How can i get that? or how can i separate the matrix in vectors and so delete de nan's? Tanks

   A = [5 4 3 2 1;NaN 4 3 2 1;NaN NaN 3 2 1] ;
   idx = isnan(A) ;
   A(idx) = 0 ;

You cannot get the result as [5 4 3 2 1; 4 3 2 1;3 2 1], because this is not a matrix. You can remove the nan's and replace with the number you want.
