Removing any row containing NaN in MATLAB

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

>> X = [ 1 2 3; 3 4 5; NaN 3 NaN]

X =

     1     2     3
     3     4     5
   NaN     3   NaN

>> X(any(isnan(X),2),:) = []

X =

     1     2     3
     3     4     5

One can make a function for it also

function X = exciseRows(X)
X(any(isnan(X),2),:) = [];
