Há 3 dias · Moore–Penrose inverse. In mathematics, and in particular linear algebra, the Moore–Penrose inverse of a matrix , often called the pseudoinverse, is the most widely known generalization of the inverse matrix. [1] It was independently described by E. H. Moore in 1920, [2] Arne Bjerhammar in 1951, [3] and Roger Penrose in 1955. [4]
Há 4 dias · A square matrix that is its own inverse, i.e. \( {\bf A} = {\bf A}^{-1} \) and \( {\bf A}^{2} = {\bf I}, \) is called an involution or involutory matrix. We list the main properties of determinants: 1.
Há 6 dias · In mathematical physics, the gamma matrices, {,,,} , also called the Dirac matrices, are a set of conventional matrices with specific anticommutation relations that ensure they generate a matrix representation of the Clifford algebra , .
Há 2 dias · Calculates an affine matrix of 2D rotation. The function calculates the following matrix: \[\begin{bmatrix} \alpha & \beta & (1- \alpha ) \cdot \texttt{center.x} - \beta \cdot \texttt{center.y} \\ - \beta & \alpha & \beta \cdot \texttt{center.x} + (1- \alpha ) \cdot \texttt{center.y} \end{bmatrix}\] where
Há 4 dias · Project description. The galois library is a Python 3 package that extends NumPy arrays to operate over finite fields. Enjoying the library? Give us a :star: on GitHub! The user creates a FieldArray subclass using GF = galois.GF(p**m) . GF is a subclass of np.ndarray and its constructor x = GF(array_like) mimics the signature of np.array().
