Element-wise logical AND operator.

Category: Language Fundamentals > Operators and Elementary Operations

Syntax

C = A & B

Description

& combines conditions on whole arrays, for example x(x > 0 & x < 10) selects the entries between 0 and 10. Both operands are always evaluated.

In an if or while condition, prefer &&, which stops as soon as the answer is known and requires scalar operands.

Input arguments

A, B

Logical or numeric arrays with compatible sizes. Any nonzero value counts as true.

Output arguments

C

Logical array of the size given by implicit expansion.

Example

x = [-2 3 8 12];
x > 0 & x < 10
x(x > 0 & x < 10)
[1 0 2] & [1 1 0]

ans = 1×4 logical array

   0   1   1   0
ans = 1×2

     3     8
ans = 1×3 logical array

   1   0   0
