The vector (a) has one index (i), indicating that it is a 1st order tensor. This is trivial for this case, but becomes useful later. Let us examine the vector dot product, which has a scalar result. Here we learn a new feature of index notation: sum over repeated indices. a·b = a 1 a 2 a ...

WebIn linear algebra, the transpose of a matrix is an operator which flips a matrix over its diagonal; that is, it switches the row and column indices of the matrix A by producing another matrix, often denoted by A T (among other notations).. The transpose of a matrix was introduced in 1858 by the British mathematician Arthur Cayley. In the case of a logical … WebMar 5, 2024 · Computing Determinants with cofactor Expansions. As noted in Section 8.2.1, it is generally impractical to compute determinants directly with Equation (8.2.1). In this section, we briefly describe the so-called cofactor expansions of a determinant. When properly applied, cofactor expansions are particularly useful for computing determinants … can i be a lawyer quiz
