Matrix

Materials

The body constituent of a composite or two-phase alloy that completely surrounds the dispersed phase and gives the body its bulk form.

Mathematics

A rectangular array of elements. The dimensions of a matrix are often written as m x n. Where m is the number of rows and n the number of columns.

Examples

2 x 2 matrix, also known as a square matrix
2 x 3 matrix
4 x 2 matrix

If we have a matrix
each element of the matrix may be referenced using the notation Ai,j
i is the row and j is the column
Then
A1,1 = 3, A2,3 = 1, A3,4 = 56
