Identity Matrix checker calculator
|
 1. `[[1,0,0],[0,1,0],[0,0,1]]`
2. `[[1,1,0],[0,1,0],[0,0,1]]`
|
Example1. is Identity Matrix ?
`[[1,0,0],[0,1,0],[0,0,1]]`Solution:A square matrix, in which all diagonal elements are unity and all other elements are zero, is called an identity matrix or a unit matrix.
Or
A diagonal matrix, in which all diagonal elements are unity, is called an identity matrix or a unit matrix. | `A` | = | | `1` | `0` | `0` | | | `0` | `1` | `0` | | | `0` | `0` | `1` | |
|
Here, all diagonal elements are unity and all other elements are zero, so it is an identity matrix or a unit matrix.
