Hello Rooters,

Is there a direct way to calculate the error of the inverse matrix?

I have a 6 x 6 matrix.

I used following lines to take a the inverse of my matrix.I am looking note/code for calculate the error of the inverse matrix efficiently?

```
matrix.Print();
TMatrixD matInv(matrix);
matInv.Invert()
matInv.Print();
```

Apology if this is a stupid question.

Thanks

Dil
