zeros(A)
zeros(A)
Create an array of all zeros with the same element type and shape as A.
Examples
julia> zeros(Char,(1,1))
1x1 Array{Char,2}:
'\0'
julia> foo = [1,2];
julia> zeros(foo)
2-element Array{Int64,1}:
0
0-
Create a 1-dimensional array of zeros with default type:
julia> zeros(5) 5-element Array{Float64,1}: 0.0 0.0 0.0 0.0 0.0This example creates a 1-dimensional array of zeros with length 5 and default type
Float64. -
Create a 2-dimensional array of zeros with specified type:
julia> zeros(Int, 2, 3) 2×3 Array{Int64,2}: 0 0 0 0 0 0It creates a 2-dimensional array of zeros with type
Intand dimensions 2x3. -
Create a 3-dimensional array of zeros with custom type:
julia> zeros(UInt8, (2, 2, 2)) 2×2×2 Array{UInt8,3}: [:, :, 1] = 0 0 0 0 [:, :, 2] = 0 0 0 0This example generates a 3-dimensional array of zeros with type
UInt8and dimensions 2x2x2.
Common mistake example:
julia> zeros(3.5)
ERROR: InexactError: Int64(Int64, 3.5)In the above example, attempting to create an array of zeros with a non-integer type (3.5) raises an InexactError. Ensure that the type provided is valid for creating an array of zeros.
