Would fail if test suite contained any Infs.

^ Yes, this happens to work on the test inputs, but is technically not doing what the problem asks.

On the other hand, B = A(all(A==A,2),:) works.

Test	Status	Code Input and Output
1	Pass	%% A = [ 1 5 8 -3 NaN 14 0 6 NaN ]; B_correct = [ 1 5 8 ]; assert(isequal(remove_nan_rows(A),B_correct))
2	Pass	%% A = 1:10; B_correct = A; assert(isequal(remove_nan_rows(A),B_correct))
3	Pass	%% A = [ 1 5 8 -3 NaN 14 0 6 6]; B_correct = [1 5 8; 0 6 6]; assert(isequal(remove_nan_rows(A),B_correct))
4	Pass	%% A = [ 1 3 6 NaN 3 NaN]'; B_correct = [1 3 6 3]'; assert(isequal(remove_nan_rows(A),B_correct))
5	Pass	%% A = [ 1 3 6 NaN; 3 4 2 1]; B_correct = [3 4 2 1]; assert(isequal(remove_nan_rows(A),B_correct))
