1. is Square Matrix ?
`[[1,2,3],[4,5,6],[7,8,9]]`Solution:A matrix, in which number of rows and number of columns are equal, is called a square matrix.
| `A` | = | | `1` | `2` | `3` | | | `4` | `5` | `6` | | | `7` | `8` | `9` | |
|
The number of rows(3) and number of columns(3) are equal, So `A` is a square matrix
2. is Square Matrix ?
`[[1,2,3],[4,5,6]]`Solution:A matrix, in which number of rows and number of columns are equal, is called a square matrix.
The number of rows(2) and number of columns(3) are not equal, So `A` is not a square matrix
