NumPy Questions et reponses d'entretien
Question 11. Explain the differences between np.dot() and np.matmul() in NumPy.
np.dot() performs matrix multiplication for 2-D arrays, while np.matmul() is equivalent to the '@' operator and is more general.
Question 12. Create a diagonal matrix using NumPy.
import numpy as npnarr = np.diag([1, 2, 3])
Question 13. Explain the purpose of np.meshgrid() in NumPy.
np.meshgrid() is used to create coordinate matrices from coordinate vectors, commonly used for 3D plotting.
Question 14. How to find the dimension of a NumPy array?
You can use the attribute 'ndim'. For example, if 'arr' is your array, use 'arr.ndim'.
Question 15. What is the difference between 'np.zeros()' and 'np.ones()' in NumPy?
'np.zeros()' creates an array filled with zeros, while 'np.ones()' creates an array filled with ones.
