Initialization

Create NDArrays with the usual Julia-style constructors. The default element type is Float32 unless you pass one.

using cuNumeric

# Zeros / ones / fill
Z = cuNumeric.zeros(4, 4)                 # Float32 by default
Z64 = cuNumeric.zeros(Float64, 4, 4)
O = cuNumeric.ones(3, 3)
F = cuNumeric.fill(7.5f0, (2, 3))

# Boolean arrays
T = cuNumeric.trues(2, 3)
Fbool = cuNumeric.falses(2, 3)

# Identity
I = cuNumeric.eye(5)
I16 = cuNumeric.eye(Float32, 5)

# Uniform random values (default Float32; backend draws Float64 then converts)
R = cuNumeric.rand(4, 4)
R64 = cuNumeric.rand(Float64, 1000)
cuNumeric.rand!(R64)                      # fill an existing Float64 array

Shapes can be passed as separate Ints or as a Tuple / Dims:

cuNumeric.zeros(2, 3)
cuNumeric.zeros((2, 3))
cuNumeric.ones(Float64, (10, 10))
