Remove rows that contain NaN

I am currently trying to remove all rows that contain a NaN.
In other words, if you are given this input : A = [ 1 5 8; -3 NaN 14; 0 6 NaN]
The output should be: B = [1 5 8]
This is what I have so far, but I keep getting an error saying the ii index cannot exceed 1.
A = [ 1 5 8
-3 NaN 14
0 6 NaN ];
B = remove_nan_rows(A)
function B = remove_nan_rows(A)
[row,column] = size(A);
for ii = 1:row
for jj = 1:column
if isnan(A(ii,jj)) == 1
A(ii,:) = [];
end
end
end
B = A;
end

B=A;
B(any(isnan(B),2),:)=[]

Yeah, good catch. Also, there are some circumstances where you can remove an element from a matrix such as
a = 1:10;
a(2) = [];
so i'll remove that comment to avoid confusion.
