matrixcomponenten
Matrixcomponenten, in mathematics and linear algebra, refer to the individual entries of a matrix. An m×n matrix A is defined by its components a_ij, where i = 1,...,m denotes the row and j = 1,...,n denotes the column. Thus A = [a_ij]. Each a_ij is a scalar and together they determine all properties of A.
In addition to being single numbers, the rows and columns of a matrix are themselves components of
Matrix operations act componentwise: addition and subtraction add corresponding entries, and scalar multiplication multiplies each component
For square matrices, diagonal components a_ii play a special role; the trace is the sum of diagonal
In practice, components are stored in memory as a two-dimensional array; many computations use vectorization by
