How do I use NumPy to transpose a matrix?

You can use the numpy.transpose() function or the .T attribute to transpose a matrix in NumPy.

Can you show me an example of transposing a 2D array?

Sure! Here's an example:

import numpy as np

matrix = np.array([[1, 2, 3], [4, 5, 6]])
transposed_matrix = np.transpose(matrix)
print(transposed_matrix)

This will output:

[[1 4]
 [2 5]
 [3 6]]

What if I have a 3D array? How does transposing work then?

For a 3D array, you can still use numpy.transpose(), but you can specify the axes you want to permute. For example:

array_3d = np.random.rand(2, 3, 4)
transposed_3d = np.transpose(array_3d, (1, 0, 2))

Are there any other methods to transpose a matrix in NumPy?

Yes, you can also use the .swapaxes() method to swap specific axes of the array, which can achieve similar results depending on your needs.
