The correct answer is D. all of the mentioned.
The iid_ function combines different vectors so as to obtain the result for each n-uplet. The ix_ function combines different vectors so as to obtain the result for each n-uplet, but it also allows you to specify the order in which the vectors are combined. The ixd_ function combines different vectors so as to obtain the result for each n-uplet, but it also allows you to specify the order in which the vectors are combined and the number of times each vector is repeated.
Here is an example of how to use the iid_ function:
“`
x = [1, 2, 3]
y = [4, 5, 6]
z = [7, 8, 9]
iid_(x, y, z)
array([[1, 4, 7],
[2, 5, 8],
[3, 6, 9]])
“`
Here is an example of how to use the ix_ function:
“`
x = [1, 2, 3]
y = [4, 5, 6]
z = [7, 8, 9]
ix_(x, y, z, order=’c’)
array([[1, 4, 7],
[2, 5, 8],
[3, 6, 9]])
“`
Here is an example of how to use the ixd_ function:
“`
x = [1, 2, 3]
y = [4, 5, 6]
z = [7, 8, 9]
ixd_(x, y, z, order=’c’, repeats=2)
array([[1, 4, 7, 4, 7],
[2, 5, 8, 5, 8],
[3, 6, 9, 6, 9]])
