	        is Identity Matrix 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.
