Find logical AND
A & B & ...
and(A, B)
A & B & ...
performs
a logical AND of all input arrays A
, B
,
etc., and returns an array containing elements set to either logical
1 (true
) or logical 0 (false
).
An element of the output array is set to 1 if all input arrays contain
a nonzero element at that same array location. Otherwise, that element
is set to 0.
Each input of the expression can be an array or can be a scalar value. All nonscalar input arrays must have equal dimensions. If one or more inputs are an array, then the output is an array of the same dimensions. If all inputs are scalar, then the output is scalar.
If the expression contains both scalar and nonscalar inputs,
then each scalar input is treated as if it were an array having the
same dimensions as the other input arrays. In other words, if input A
is
a 3-by-5 matrix and input B
is the number 1, then B
is
treated as if it were a 3-by-5 matrix of ones.
and(A, B)
is called for
the syntax A
&
B
when
either A
or B
is an object.
