| Back | [latex]For any size square matrix, the {\bf identity} matrix $I$ is the matrix with $1$ on the main diagonal, and zeros off the main diagonal. That is,$$I=\begin{bmatrix} 1 &0 &0 &\cdots &0 \\0 &1 &0 &\cdots &0 \\0 &0 &1 &\cdots &0 \\\vdots &\vdots &\vdots &\ddots &\vdots \\0 &0 &0 &\cdots &1 \end{bmatrix}.$$For any square matrix $A$, $IA=AI=A$, for the corresponding size of $I$.[/latex] |
