Hi All,

I have a problem in working out the inverse of a CMatrix when its determinant is very small (less than 1e-200). I copied the result of GetString() method into Matlab, and finally got the inverse and determinant of my Matrix there. Matlab responded properly whereas CMatrix3.1 had shown me this message: "Matrix cannot be inverted".
I am guessing the problem lies in accuracy of 'Double' variable of Visual Basic 6.0, the language I am writing my code with. Anybody has a better idea? And if you guess so, may you tell me how to solve this problem?

Thanx in advance,
Reza.
