How can I remove all rows from a matrix which contain NaN values?

For example:

>> A = [1, 2, 3; 4, NaN, 6; 7, 8, 9];

In matrix A defined above, I would like to remove row 2 ([4, NaN, 6]).

Use the following code to remove all rows which contain NaN values from a matrix A:
>> A = [1, 2, 3; 4, NaN, 6; 7, 8, 9];
>> A = A(~any(isnan(A), 2), :);

A = [1, 2, 3; 4, NaN, 6; 7, 8, 9];
A = rmmissing(A)
A = 2×3
1 2 3 7 8 9
