rand

Default random

inline fun <reified T : Number> Multik.rand(dim0: Int): D1Array<T>
inline fun <reified T : Number> Multik.rand(dim0: Int, dim1: Int): D2Array<T>
inline fun <reified T : Number> Multik.rand(dim0: Int, dim1: Int, dim2: Int): D3Array<T>
inline fun <reified T : Number> Multik.rand(
    dim0: Int, dim1: Int, dim2: Int, dim3: Int
): D4Array<T>

From shape array

inline fun <reified T : Number, reified D : Dimension> Multik.rand(
    shape: IntArray
): NDArray<T, D>

Default distribution by type:

Type	Range
`Int`	`[Int.MIN_VALUE, Int.MAX_VALUE)`
`Long`	`[Long.MIN_VALUE, Long.MAX_VALUE)`
`Float`	`[0.0, 1.0)`
`Double`	`[0.0, 1.0)`

Random in range

inline fun <reified T : Number, reified D : Dimension> Multik.rand(
    from: T, until: T, vararg dims: Int
): NDArray<T, D>

inline fun <reified T : Number, reified D : Dimension> Multik.rand(
    from: T, until: T, dims: IntArray
): NDArray<T, D>

Generates values uniformly distributed in [from, until).

Random with seed

inline fun <reified T : Number, reified D : Dimension> Multik.rand(
    seed: Int, from: T, until: T, vararg dims: Int
): NDArray<T, D>

inline fun <reified T : Number, reified D : Dimension> Multik.rand(
    seed: Int, from: T, until: T, dims: IntArray
): NDArray<T, D>

Random with generator

inline fun <reified T : Number, reified D : Dimension> Multik.rand(
    gen: Random, from: T, until: T, vararg dims: Int
): NDArray<T, D>

inline fun <reified T : Number, reified D : Dimension> Multik.rand(
    gen: Random, from: T, until: T, dims: IntArray
): NDArray<T, D>

Parameters

Parameter	Type	Description
`dim0..dim3`	`Int`	Axis sizes. Must be positive.
`dims`	`IntArray` or `vararg Int`	Shape of the output array.
`from`	`T`	Lower bound (inclusive).
`until`	`T`	Upper bound (exclusive).
`seed`	`Int`	Seed for the random generator.
`gen`	`Random`	Custom `kotlin.random.Random` instance.

Example

val a = mk.rand<Double>(3, 3)                     // 3×3, values in [0.0, 1.0)
val b = mk.rand<Int, D1>(from = 1, until = 100, 10)  // 10 ints in [1, 100)
val c = mk.rand<Double, D2>(42, 0.0, 1.0, 3, 3)  // seeded 3×3
