The variable is then used to create a constraint over two of the indices and to sum the multiplication with a two-dimensional matrix.

These rules usually take two variables as input, mapping cleanly to a two-dimensional matrix, although theoretically a matrix of any number of dimensions is possible.

The set of all orthogonal two-dimensional matrices together with matrix multiplication form the orthogonal group: O(2).

A two-dimensional Boolean matrix, in which the rows represent the vertices and columns represent the edges.

These groups are readily constructed with two-dimensional orthogonal matrices.

Two factors (crankshaft speed and engine load) are used to index into a two-dimensional matrix of numeric values known as the "fuel map".

Used in latent semantic analysis, stores the occurrences of words in documents in a two-dimensional sparse matrix.

The nuclear lamina consist of a two-dimensional matrix of proteins located next to the inner nuclear membrane.

The second method, after Gross [1985], uses a lexicon-grammar, in the form of a two-dimensional matrix.

For example, the tensor product of two two-dimensional square matrices:
