Get number of elements of array in Julia – length() Method
The length()
is an inbuilt function in julia which is used to return the number of elements present in the specified array.
Syntax: length(A::AbstractArray)
Parameters:
- A: Specified array
Returns: It returns the number of elements present in the specified array.
Example 1:
# Julia program to illustrate # the use of Array length() method # Finding the number of elements present in # the specified 1D array A. A = [ 5 , 10 , 15 , 20 ] println(length(A)) # Finding the number of elements present in # the specified 2D array B of size 2 * 2 B = [ 5 10 ; 15 20 ] println(length(B)) # Finding the number of elements present in # the specified 3D array C of size 2 * 2*2 C = cat([ 1 2 ; 3 4 ], [ 5 6 ; 7 8 ], [ 9 10 ; 11 12 ], dims = 3 ) println(length(C)) |
Output:
Example 2:
# Julia program to illustrate # the use of Array length() method # Finding the number of elements present in # the specified 1D array A. A = [ 1 , 2 , 3 ]; println(length(A)) # Finding the number of elements present in # the specified 2D array B of size 2 * 2 B = [ 2 4 ; 6 8 ; 10 12 ]; println(length(B)) # Finding the number of elements present in # the specified 3D array C of size 2 * 2*2 C = cat([ 1 2 ; 3 4 ], [ 5 6 ; 7 8 ], [ 9 10 ; 11 12 ], [ 13 14 ; 15 16 ], dims = 4 ); println(length(C)) |
