np sign code example
Example 1: signum numpy
# x is the array
np.sign(x)
Example 2: at sign numpy
A = np.random.random((n, n))
B = np.random.random((n, n))
C = A @ B #multi matrix A and B
# x is the array
np.sign(x)
A = np.random.random((n, n))
B = np.random.random((n, n))
C = A @ B #multi matrix A and B
