Hessian Matrix Determinant and Convex/Concave

I have a function which has a Hessian Matrix of:

-2	0	0
0	-16	10
0	10	-4

Can anyone explain why this is neither a positive nor a negative definite?

And could you please explain 2*2 and 3*3 Hessian's rule of determining positive/negative definite? Thank you.

Matlab You will write a function to calculate the determinant of a matrix. It should work for any size matrix. Remember that the determinant can be calculated by multiplying the diagonal elements of an upper right triangular matrix. Your function will take a matrix passed to it and put it in upper right triangular form. You will work down the diagonal beginning at row 1 column 1, then row 2 column 2, etc. Note that the row and column numbers...
