Hi,

I have a vector t which contains either numerical values or NaNs. I want to take out all NaNs, ie, t=t("~NaN"); Is there a syntax to do this? (i can do this with t=t(t>=0 or t<0), i guess, but wonder if there is a direct way to obtain it..)

Thanks

well... you got it almost right...

one of the solutions

v=[1,nan,2,nan];
r=v(~isnan(v))
% r = 1 2
% -or-
r=v(v==v)
