How do I create a matrix using NumPy?

How do I create a matrix using NumPy?

You can create a matrix in NumPy using the numpy.array() function. For example, np.array([[1, 2], [3, 4]]) creates a 2x2 matrix.

Can I create a matrix filled with zeros?

Yes, you can use numpy.zeros((rows, columns)) to create a matrix filled with zeros. For example, np.zeros((3, 3)) creates a 3x3 matrix of zeros.

What about creating a matrix with random values?

You can use numpy.random.rand(rows, columns) to create a matrix with random values between 0 and 1. For instance, np.random.rand(2, 3) creates a 2x3 matrix with random values.

How can I change the shape of an existing matrix?

You can use the reshape() method. For example, if you have a matrix a, you can reshape it with a.reshape(new_shape).
