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

Hi Dil,

Thank you for the question.

Could it be that you are referring to the condition number of the matrix.
