function y = removeNaN(x)
[n m] = size(x);

for i = 1 : n
maxx = max(isnan(x(i,:)));
if maxx ~= 1
y = (x(i,:))
end
end

It looks like y will return only the last non-NaN row, instead of collecting all of them.

This solution doesn't necessarily work if there are any Inf elements in the matrix. Perhaps it would be best to add a test case where that is the case.
