A very vague question. I guess the answer is: yes.
x = [1, NaN, 3];
x(isnan(x)) = [];

@x: An explicite example would be much easier to understand.
If your results contain some 0/0==NaN values, it is your turn to define what should happen in this case. It is impossible for us to guess, what a good replacement could be, because this depends on your problem.
Perhaps: x(isnan(x)) = 0, or x(isnan(x)) = -1000, or whatever.
If you plot the results NaN's are often treated very handy, because they are not drawn. See:
plot([1:10, NaN, 11:16]);
