MATLAB: How To Efficiently Remove NaN Elements from Matrix

I got code that does it below but its a little slow (the matrix is big) is there a better way to do it?

errorMat=isnan(rates);
errorRows=ind(errorMat);
for i=1:length(errorRows)
   rates(:,errorRows(i)) = [];
end

Answer 1

rates(any(isnan(rates), 2), :) = [];

Alternatively:

rates = rates(~any(isnan(rates), 2), :);

I think the second approach is faster.
