The einsum() method evaluates the Einstein summation convention on the operands. Using the Einstein summation convention, many common multi-dimensional, linear algebraic array operations can be represented in a simple fashion. In implicit mode einsum computes these values. In explicit mode, einsum provides further flexibility to compute other array operations that might not be considered classical Einstein summation operations, by disabling, or forcing summation over specified subscript labels.For Array axis summations (sum over an axis) with Einstein summation convention, use the numpy.einsum() method in Python. The 1st parameter is the subscript. It specifies the subscripts for summation as comma separated list ... Read More

To return the minimum of an array or minimum ignoring any NaNs, use the numpy.nanmin() method in Python. The method returns an array with the same shape as a, with the specified axis removed. If a is a 0-d array, or if axis is None, an ndarray scalar is returned. The same dtype as a is returned.The 1st parameter, a is an array containing numbers whose minimum is desired. If a is not an array, a conversion is attempted.The 2nd parameter, axis is an axis or axes along which the minimum is computed. The default is to compute the minimum ... Read More

To return the angle of the complex argument, use the numpy.angle() method in Python. The method returns the counterclockwise angle from the positive real axis on the complex plane in the range (-pi, pi], with dtype as numpy.float64. The 1st parameter z, A complex number or sequence of complex numbers. The 2nd parameter, deg, return angle in degrees if True, radians if False (default).StepsAt first, import the required libraries −import numpy as npCreate an array using the array() method −arr = np.array([1.0, 1.0j, 1+1j]) Display the array −print("Array...", arr)Get the type of the array −print("Our Array type...", arr.dtype) Get the ...

To return the bases when first array elements are raised to powers from second array, use the float_power() method in Python Numpy. The method returns the bases in x1 raised to the exponents in x2. This is a scalar if both x1 and x2 are scalars. The parameter x1 are the bases. The parameter x2 are the exponents.Raise each base in x1 to the positionally-corresponding power in x2. x1 and x2 must be broadcastable to the same shape. This differs from the power function in that integers, float16, and float32 are promoted to floats with a minimum precision of float64 ... Read More
