Identity Matrix Definition (Unit Matrix)Ī unit matrix, or identity matrix, is a square matrix whose principal diagonal elements are ones, and the rest of the elements of the matrix are zeros. We have different types of matrices, such as rectangular matrices, square matrices, triangular matrices, symmetric matrices, etc. For example, the matrix given below is a “3 × 4” matrix, i.e., a matrix that has three rows and four columns. A matrix is said to be an “m by n” matrix when it has “m” rows and “n” columns and is written as an “m × n” matrix. The size of a matrix can be determined by the number of rows and columns in it. A matrix is defined as a rectangular array of numbers that are arranged in rows and columns.
