Getting tuple or range of the valid indices in Julia – axes() Method

The axes() is an inbuilt function in julia which is used to return the tuple or valid range of valid indices for specified array.

Syntax:
axes(A)
or
axes(A, d)

Parameters:

• A: Specified array.
• d: Specified dimension.

Returns: It returns the tuple or valid range of valid indices for specified array.

Example 1:

# Julia program to illustrate
# the use of Array axes() method

# Getting tuple for 1D array of size 5
# with each element filled with value 4
println(axes(fill(4, (5))))

# Getting tuple for 2D array of size 2X3
# with each element filled with value 5
println(axes(fill(5, (2, 3))))

# Getting tuple for 3D array of size 2X3X4
# with each element filled with value 4
println(axes(fill(4, (2, 3, 4))))

Output:

Example 2:

# Julia program to illustrate
# the use of Array axes() method

# Getting tuple for 1D array of size 5
# with each element filled with value 4
# along with dimension of 1
A = fill(4, (5));
println(axes(A, 1))

# Getting tuple for 2D array of size 2X3
# with each element filled with value 5
# along with dimension of 2
B = fill(5, (2, 3));
println(axes(B, 2))

# Getting tuple for 3D array of size 2X3X4
# with each element filled with value 4
# along with dimension of 3
C = fill(4, (2, 3, 4));
println(axes(C, 3))

Output:
