NaN happens in case of Inf/Inf, 0/0, Inf-Inf etc. One way to avoid this is to explicitly write a check, an if - else check maybe, wherever a similar situation could possibly arrive. Or you can use an assert statement, where you can stop execution if the condition asserted is false. In Matlab, it is achieved by I know I can use isnan to check for individual elements, such as for i1:m for j1:n if isnan(A(i,j)) ), I just get 1 0 1.
