6 matrix
1) матрицапрямоугольный двумерный массив чисел, символов, точек или других объектов; двумерная таблица, состоящая из строк и столбцов. Так как каждый элемент матрицы находится на пересечении строки и столбца, он адресуется указанием соответствующих им номеров. Над матрицами можно производить арифметические и другие действия.Syn:см. тж. access matrix, adjacency matrix, array, band matrix, dot matrix, dynamic array, inverse matrix, invertible matrix, main diagonal, matrix inversion, matrix keypad, matrix multiply, matrix rank, matrix switch, resistive matrix, singular value, sparse matrix, square matrix, stochastic matrix, submatrix, symmetric matrix, transition matrix, transpose matrix, zero matrix2) матрица, формаформообразующая оснастка, используется, например, для формования изделий из стеклопластика или отливок из сплавов либо искусственного камня3) см. switching matrix4) матричныйАнгло-русский толковый словарь терминов и сокращений по ВТ, Интернету и программированию. > matrix

Submatrix — In mathematics, a submatrix is a matrix formed by selecting certain rows and columns from a bigger matrix. That is, as an array, it is cut down to those entries constrained by row and column. For example: mathbf{A}=egin{bmatrix} a {11} a {12} a… … Wikipedia
