Mojo function

randn

randn[dtype: DType](ptr: UnsafePointer[Scalar[dtype], ptr.origin, address_space=ptr.address_space], size: Int, mean: Float64 = 0, standard_deviation: Float64 = 1)

Fills memory with random values from a Normal distribution.

Example:

from std.random import randn, seed
from std.memory import alloc

seed()
var size: Int = 10
var ptr = alloc[Float64](size)
randn[DType.float64](ptr, size, mean=0.0, standard_deviation=1.0)
for i in range(size):
    print(ptr[i])  # Random Float64 from Normal(0.0, 1.0)
ptr.free()

Constraints:

The type should be floating point.

Parameters:

dtype (DType): The dtype of the pointer.

Args:

ptr (UnsafePointer): The pointer to the memory area to fill.
size (Int): The number of elements to fill.
mean (Float64): The mean of the normal distribution.
standard_deviation (Float64): The standard deviation of the normal distribution.
