MATLAB Function Reference 
Find logical AND of array or scalar inputs
Syntax
Description
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 3by5 matrix and input B
is the number 1, then B
is treated as if it were a 3by5 matrix of ones.
and(A, B)
is called for the syntax A
&
B
when either A
or B
is an object.
Note
The symbols & and && perform different operations in MATLAB. The elementwise AND operator described here is & . The shortcircuit AND operator is && .
