How To Take Inverse Of A Matrix In Matlab®?

>> a = [1 3 5;7 8 11;100 1 4];
b =inv(a)
c = inv(a).*5
d = inv(a)+3

b =

   -0.0288    0.0096    0.0096
   -1.4725    0.6813   -0.0330
    1.0893   -0.4107    0.0179


c =

   -0.1442    0.0481    0.0481
   -7.3626    3.4066   -0.1648
    5.4464   -2.0536    0.0893


d =

    2.9712    3.0096    3.0096
    1.5275    3.6813    2.9670
    4.0893    2.5893    3.0179

To take the inverse of a matrix in Matlab®, you need to use the “inv()” command. It will generate the inverse of a matrix if you write the name of this matrix in this code in Matlab®.

‘a’ is the normal matrix created by us in Matlab® as shown above.

‘b’ is the matrix that we take as the inverse of ‘a’.

‘c’ is the multiplied inverse matrix of a that shows you can do mathematical calculations directly with inverses of matrices in Matlab®.

In ‘d’ we did the addition of an inverse matrix that also shows you can do mathematical calculations with this.

Conclusion

As you can see, taking inverses of various matrices in Matlab® is very easy and very useful.

Do not forget to leave your comments and questions below about the taking inverses of various matrices in Matlab® below.
