    • n matrix Hence That which incloses anything, or gives origin to anything, like a womb. A mold which gives form to material forced into it in a solid condition, or poured into it in a fluid state and allowed to harden before removal.
    • n matrix In mathematics, a rectangular array of quantities, usually square: so called because considered as a mold or set of compartments into which a certain number of quantities can be put, the leaving of one of the spaces unoccupied being in effect to put zero there. : The matrix is consequently a multiple quantity having as many dimensions as it has spaces. The numbers in the spaces are called the constituents of the matrix. The following definitions relate to square matrices. The vertical lines of numbers are called the columns, the horizontal ones the rows. The diagonal running from the upper left hand to the lower right hand corner is called the principal diagonal. Constituents symmetrically situated with reference to the principal diagonal are said to be conjugate. A matrix in which every constituent is equal to its conjugate is said to be symmetrical; if all the constituents along each diagonal band transverse to the principal diagonal are equal, the matrix is said to be persymmetrical. The addition of matrices is so understood that the sum of two like matrices is a matrix every constituent of which is equal to the sum of the corresponding constituents of the parts. The multiplication of two like square matrices is so understood that the product is a matrix whose construction is of the kind shown in the following example
    • n matrix a matrix with p columns and q rows. The types of two matrices are said to be complementary when p—p = q + q.
