Matrix (mathematics) - Wikipedia In mathematics, a matrix (pl : matrices) is a rectangular array of numbers or other mathematical objects with elements or entries arranged in rows and columns, usually satisfying certain properties of addition and multiplication For example, denotes a matrix with two rows and three columns
Matrices - Math is Fun We talk about one matrix, or several matrices There are many things we can do with them To add two matrices: add the numbers in the matching positions: These are the calculations: The two matrices must be the same size, i e the rows must match in size, and the columns must match in size
