Assuming your input is a table:
nantable = yourtable(isnan(yourtable{:, 5}), :) %keep all rows whose 5th column is nan

If the tables all contain the same variable names (headers), use the variable names to index columns rather than column number. This is one of the strengths of tables over matrices and cell arrays. If the variable names are different, then you'll have to use numeric indexing.
Suppose column 5 is named "MyData" and the table is named "T".
nanIdx = isnan(T.MyData);
% If you must use numeric indexing,
% nanIdx = isnan(T{:,5});
Create the new table
Tnew = T(nanIdx,:);
