MATLAB: Delete rows for specific elements from a matrix

delete elementmatrix

Hi
I'm trying to delete all rows if the second and third element is equal to zero. My if-else sentence doesn't work. Could you help me?
f = [2 5 4 3 2; 4 9 2 1 9; 2 0 0 0 0; 4 0 0 0 3; 9 7 12 14 42];
for i = 1:length(f)
    if (f(i,2) == 0) && (f(i,3) == 0)
        f(i,:) = [];
    end
end
A = f; % Want the final result of A to look like this: A = [2 5 4 3 2; 4 9 2 1 9; 9 7 12 14 42]

Best Answer

f = [2 5 4 3 2; 4 9 2 1 9; 2 0 0 0 0; 4 0 0 0 3; 9 7 12 14 42];
f(all(~f(:,2:3),2),:)=[]
%or
f=f(any(f(:,2:3),2),:)
