To subtract one polynomial to another, use the numpy.polynomial.polynomial.polysub() method in Python. Returns the difference of two polynomials c1 + c2. The arguments are sequences of coefficients from lowest order term to highest, i.e., [1, 2, 3] represents the polynomial 1 + 2*x + 3*x**2.The method returns the coefficient array ... Read More

To add one polynomial to another, use the numpy.polynomial.polynomial.polyadd() method in Python. Returns the sum of two polynomials c1 + c2. The arguments are sequences of coefficients from lowest order term to highest, i.e., [1, 2, 3] represents the polynomial 1 + 2*x + 3*x**2.The method returns the coefficient array ... Read More

To compute the inverse of a 3D array, use the numpy.linalg.tensorinv() method in Python. The result is an inverse for a relative to the tensordot operation tensordot(a, b, ind), i. e., up to floating-point accuracy, tensordot(tensorinv(a), a, ind) is the “identity” tensor for the tensordot operation. The method returns a’s ... Read More

To compute the inverse of a Four-Dimensional array, use the numpy.linalg.tensorinv() method in Python. The result is an inverse for a relative to the tensordot operation tensordot(a, b, ind), i. e., up to floating-point accuracy, tensordot(tensorinv(a), a, ind) is the “identity” tensor for the tensordot operation.The method returns a’s tensordot ...

To compute the multiplicative inverse of a matrix object with matrix(), use the numpy.linalg.inv() method in Python. Given a square matrix a, return the matrix ainv satisfying dot(a, ainv) = dot(ainv, a) = eye(a.shape[0]).The method returns (Multiplicative) inverse of the matrix a. The 1st parameter, a is a Matrix to ... Read More

To Compute the (Moore-Penrose) pseudo-inverse of a stack of matrices, use the numpy.linalg.pinv() method in Python. Calculate the generalized inverse of a matrix using its singular-value decomposition (SVD) and including all large singular values.The 1st parameter, a is a Matrix or stack of matrices to be pseudo-inverted. The 2nd parameter, ... Read More

To return the element-wise square of the array input, use the numpy.square() method in Python. The method returns the element-wise x*x, of the same shape and dtype as x. This is a scalar if x is a scalar.The 1st parameter, x is the input data. The 2nd parameter, out is ... Read More
