Skew-symmetric Matrix

In mathematics, and in particular linear algebra, a skew-symmetric (or antisymmetric or antimetric) matrix is a square matrix A whose transpose is also its negative; that is, it satisfies the equation A = −AT. If the entry in the i th row and j th column is aij, i.e. A = (aij) then the skew symmetric condition is aij = −aji. For example, the following matrix is skew-symmetric: $begin{bmatrix} 0 & 2 & -1 \ -2 & 0 & -4 \ 1 & 4 & 0end{bmatrix}.$

### Famous quotes containing the word matrix:

As all historians know, the past is a great darkness, and filled with echoes. Voices may reach us from it; but what they say to us is imbued with the obscurity of the matrix out of which they come; and try as we may, we cannot always decipher them precisely in the clearer light of our day.
Margaret Atwood (b. 1939)
