and

Element-wise logical AND operation

Usage

and(A, B)

• A and B should be real numeric arrays with compatible sizes.
• It does not work if any one of the inputs is complex.
• If the inputs have different but compatible sizes, one of them will be expanded to match the size of the other one. In particular, if one of the inputs is scalar, it compares this scalar with each element of the other input.
• An element of the output is assigned logical 1 if the corresponding elements of A and B are both non-zero, and is assigned logical 0 if otherwise.
• It gives the same result as A && B and A & B.

Example

• and(a,b) where a and b have the same sizes.

Input

a = randi(3,3,4) - 2
b = randi(3,3,4) - 2
and(a,b)

Output

a =
-1.000   1.000  -1.000  -1.000
-1.000   1.000   0.000   0.000
 0.000   1.000   0.000   0.000

b =
-1.000   0.000   0.000   1.000
 1.000   0.000  -1.000   0.000
 0.000   0.000  -1.000   1.000
