Matrix Operation

Now lets get serious with matrices shall we??

Right....
I shall go through  some of the commands of Matrix operation...
1) Inverse of a matrix...
        Simple as it sounds just use the command inv(<matrix name>) shall give you the output as the inverse of the matrix

2)Determinant of matrix
      det(<matrix name>)

3)eigenvalues of a matrix
     eig(<matrix name>)

4)How to make an Identity matrix??
  Its very easy eye(<size of matrix>)
 
   like eye(2)... gives a 2by2 Identity matrix and eye(2,3) gives an identity matrix of size 2by3

Isn't it fun??
