any

Test if any elements are nonzero

Syntax

B = any(A)
B = any(A, dim)

Description

Returns 1 if any element of A is nonzero, 0 otherwise. With a dimension argument, operates along that dimension.

Parameters

NameDescription
AInput array (scalar or NDArray)
dim(optional)Dimension to operate along (1-indexed)

Returns

1 if any element is nonzero, 0 otherwise

Examples

Try It
>> any([0 0 1 0])
1
Try It
>> any([0 0 0])
0
Try It
>> A = [1 0; 0 0]; any(A, 1)
