`|`

Element-wise logical OR operator.

Category: Language Fundamentals > Operators and Elementary Operations

Syntax

C = A | B

Returns 1 where A or B (or both) is nonzero. Same as or(A, B).

Description

| combines conditions on whole arrays: x(x < 0 | x > 10) selects the entries outside the interval [0, 10]. Both operands are always evaluated.

For scalar conditions in if and while, || is usually preferable because it skips the second test when the first is already true.

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 = [-5 3 8 15];
x < 0 | x > 10
x(x < 0 | x > 10)
[1 0 0] | [0 0 2]

Output

ans = 1×4 logical array

   1   0   0   1
ans = 1×2

    -5    15
ans = 1×3 logical array

   1   0   1
