size(ML) = 1001 x 1001

Below the end of the matrix is shown, to give an idea of the magnitude of the values:

Code:

```
-0.0096 1.0192 -0.0096 0 0
0 -0.0096 1.0192 -0.0096 0
0 0 -0.0096 1.0192 -0.0096
0 0 0 0 1.0000
```

**inv(ML)**results in a 1001x1001 matrix with values NaN.

So I tried

**(ML)\(MR)**, but that gives error: "Matrix is singular, close to singular or badly scaled. Results may be inaccurate. RCOND = NaN."

Inverting a almost similar symmetrical tri-diagonal matrix is no problem.

**So is it possible to do this inversion**?

I would be really grateful with some help!
