inline fun <T, D : Dimension> MultiArray<T, D>.any(

): Boolean

Parameters

Parameter	Type	Description
`predicate`	`(T) -> Boolean`	Condition to test each element against.

Returns:

Without predicate: true if the array is not empty.
With predicate: true if at least one element satisfies predicate. Returns false for empty arrays.

Example

val a = mk.ndarray(mk[1, 2, 3, 4])
