How to filter out rows with NaNs from one variable and the same rows from another variable without NaNs.

I have a numerical variable X [506x24706] and a numerical variable Y [506x1]. Variable Y includes some NaNs. How can I filter out rows with NaNs from Y and at the same time filter out the same corresponding rows from X and create a new Y and a new X?

 indx = isnan(Y);
 Y(indx) = [];
 X(indx,:) = [];
