How to delete, in a logical values matrix, rows that contain two or more false values (zero)?

Hello everyone! I explain my problem, trying to be as clear as possible.

I have a matrix, called "faces_logical", whose each row contains a triplet of logical values. For example:

faces_logical = [0 0 0; 0 0 0; 0 0 1; 0 0 0; 1 0 1; 1 1 1; 1 1 1; 1 1 0; 0 0 1; 0 0 1; 0 0 0];

Does exist a function in MATLAB, which allows me to obtain a vector of logical values that returns:

• "0" for every row containing or [0 0 0] or two zeros (i.e. [0 0 1], [0 1 0], [1 0 0])
• "1" for every row containing or [1 1 1] or one zero (i.e. [0 1 1], [1 0 1], [1 1 0])?

So, for the written above "faces_logical", the vector shoulds return:

[0 0 0 0 1 1 1 1 0 0 0].

Thank you in advance.

A single function, no, but you can obtain your desired output easily enough.

faces_logical = [0 0 0; 0 0 0; 0 0 1; 0 0 0; 1 0 1; 1 1 1; 1 1 1; 1 1 0; 0 0 1; 0 0 1; 0 0 0];
out = sum(faces_logical,2)>1

out = 11×1 logical array
   0
   0
   0
   0
   1
   1
