O que (quem) é symmetric array - definição

MATRIX EQUAL TO ITS TRANSPOSE
Symmetric matrices; Symmetric (matrix); Symmetric array; Symmetrizable matrix; Autonne–Takagi factorization; Autonne-Takagi factorization; Takagi factorization; Real symmetric matrix; Complex symmetric matrix
  • Symmetry of a 5×5 matrix

Dynamic array         
  • Θ(''n'')}} time, labelled with turtles). The ''logical size'' and ''capacity'' of the final array are shown.
RANDOM-ACCESS, VARIABLE-SIZE LIST DATA STRUCTURE THAT ALLOWS ELEMENTS TO BE ADDED OR REMOVED
Growable array; Dynamic table; Array list; ArrayList; Resizable array; Resizeable array; Arraylist; Mutable array
In computer science, a dynamic array, growable array, resizable array, dynamic table, mutable array, or array list is a random access, variable-size list data structure that allows elements to be added or removed. It is supplied with standard libraries in many modern mainstream programming languages.
Elementary symmetric polynomial         
HOMOGENEOUS SYMMETRIC POLYNOMIAL IN WHICH EACH POSSIBLE MONOMIAL OCCURS EXACTLY ONCE WITH COEFFICIENT 1
Elementary symmetric function; Elementary symmetric polynomials; Fundamental theorem of symmetric polynomials; Fundamental Theorem of Symmetric Polynomials
In mathematics, specifically in commutative algebra, the elementary symmetric polynomials are one type of basic building block for symmetric polynomials, in the sense that any symmetric polynomial can be expressed as a polynomial in elementary symmetric polynomials. That is, any symmetric polynomial is given by an expression involving only additions and multiplication of constants and elementary symmetric polynomials.
Array (data structure)         
DATA STRUCTURE
Ragged arrays; Array index; Vector data structure; Array element; Two-dimensional array; One-dimensional array; Vector (Computer Science); Static array; Array data structure; Vector (data structure)
In computer science, an array is a data structure consisting of a collection of elements (values or variables), each identified by at least one array index or key. An array is stored such that the position of each element can be computed from its index tuple by a mathematical formula.

Symmetric matrix

In linear algebra, a symmetric matrix is a square matrix that is equal to its transpose. Formally,

Because equal matrices have equal dimensions, only square matrices can be symmetric.

The entries of a symmetric matrix are symmetric with respect to the main diagonal. So if a i j {\displaystyle a_{ij}} denotes the entry in the i {\displaystyle i} th row and j {\displaystyle j} th column then

for all indices i {\displaystyle i} and j . {\displaystyle j.}

Every square diagonal matrix is symmetric, since all off-diagonal elements are zero. Similarly in characteristic different from 2, each diagonal element of a skew-symmetric matrix must be zero, since each is its own negative.

In linear algebra, a real symmetric matrix represents a self-adjoint operator represented in an orthonormal basis over a real inner product space. The corresponding object for a complex inner product space is a Hermitian matrix with complex-valued entries, which is equal to its conjugate transpose. Therefore, in linear algebra over the complex numbers, it is often assumed that a symmetric matrix refers to one which has real-valued entries. Symmetric matrices appear naturally in a variety of applications, and typical numerical linear algebra software makes special accommodations for them.
