`and`

Logical AND, the function form of the operator &.

Category: Symbolic Computations in MATLAB > Operators and Elementary Operations

Syntax

C = and(A, B)

Same as A & B.

Description

The result is true at positions where both operands are nonzero. The operands may be numbers or logicals, and the usual size compatibility applies, so a scalar is combined with every element of an array.

For if and while conditions with scalars, && is usually preferred because it short-circuits; and and & always evaluate both sides.

Input arguments

A, B: Numeric or logical arrays with compatible sizes. Nonzero means true.

Output arguments

C: Logical array: true where both inputs are nonzero.

Example

Elementwise AND

and([1 0 1], [1 1 0])
and(true, false)
x = 1:6;
x(and(x > 2, x < 5))

Output

ans = 1×3 logical array

   1   0   0
ans = logical
   0
ans = 1×2

     3     4

Notes

Symbolic operands are not supported (and(x > 1, x < 3) raises an error), and and takes exactly two arguments in MatLivre; three or more raise an error.
