Example – Print rows of the matrix

  1. import numpy as np.
  2. mat1 = np.array([[14, 60, 29], [35, -10, 13], [4,8,12]])
  3. print(mat1[0]) #first row.
  4. print(mat1[1]) # the second row.
  5. print(mat1[-1]) # -1 will print the last row.

  2. subtract() − subtract elements of two matrices.
  3. divide() − divide elements of two matrices.
  4. multiply() − multiply elements of two matrices.
  5. dot() − It performs matrix multiplication, does not element wise multiplication.

What is the difference between Numpy array and matrix?

The matrix objects are a subclass of the numpy arrays (ndarray). The matrix objects inherit all the attributes and methods of ndarry. Another difference is that numpy matrices are strictly 2-dimensional, while numpy arrays can be of any dimension, i.e. they are n-dimensional.
