contains

Checks whether the array contains the specified element. Because it is declared as an operator function, you can use the idiomatic element in array syntax.

Signature

operator fun <T, D : Dimension> MultiArray<T, D>.contains(element: T): Boolean

Parameters

Parameter	Type	Description
`element`	`T`	The element to search for.

Returns: true if the element is found anywhere in the array.

Example

val a = mk.ndarray(mk[1, 2, 3, 4, 5])

a.contains(3)    // true
3 in a           // true  (operator syntax)
10 in a          // false
