- This is from Shen-yeh Chen, for further discription of the problem.
-
- I am sorry, I have made a stupid mistake. What I want to ask is
-
- CHOLESKY METHOD FOR NON-POSITIVE DEFINITE MATRIX
-
- Non-positive does not mean negative. I am sorry about this.
-
- Let me state this again :
-
- 1) Is there any method I can use to REDUCE [K], and still solve the system
- when [K] is NOT POSITIVE-DEFINITE?
- 2) If such method exists, what's the criteria for positive- or nonpositive
- definite?
- 3) Does any body know how to use Gauss method to reduce [K] ??
