Provided Methods

fn randn(shape: impl ToVec<usize>) -> Self

where T: FloatDataType,

Samples an NdArray with the specified shape from a standard normal distribution (0 mean, unit standard deviation).

Examples

let ndarray = NdArray::<f64>::randn([2, 3]);
println!("{:?}", ndarray);

fn rand(shape: impl ToVec<usize>) -> Self

where T: FloatDataType,

Samples an NdArray with the specified shape with values uniformly distributed in [0, 1).

Examples

let ndarray = NdArray::<f64>::rand([2, 3]);
println!("{:?}", ndarray);

fn uniform(shape: impl ToVec<usize>, low: T, high: T) -> Self

where T: FloatDataType,

Samples an NdArray with the specified shape with values uniformly distributed in [low, high).

Examples

let ndarray = NdArray::<f64>::uniform([2, 3], -5.0, 3.0);
println!("{:?}", ndarray);

fn randint(shape: impl ToVec<usize>, low: T, high: T) -> Self

where T: NumericDataType,

Samples an NdArray with the specified shape with integer values uniformly distributed between low (inclusive) and high (exclusive).

Examples

let ndarray = NdArray::<isize>::randint([2, 3], -5, 3);
println!("{:?}", ndarray);

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
