Matrix
- 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
- i is the row and j is the column
- A1,1 = 3, A2,3 = 1, A3,4 = 56
