- To the math gurus out in netland...
-
- I am trying to construct square matrices in higher dimensions and
- compute their determinants. The order of the matrix is fixed.
- For example,
-
-
- - -
- | a b |
- | |
- | c d |
- - -
-
- is a plain-vanilla 2x2 matrix. No problems with its determinant.
- Its more sophisticated cousin, a 2nd order matrix in one higher
- dimension would be:
-
- p------q
- /| /|
- / | / |
- / | / |
- a------b |
- | | | |
- | r--|---s
- | / | /
- | / | /
- c------d
-
- The determinant of this matrix cube would be, I think,
- sum (with proper signs attached) of products of the form
-
- a s, b r, c q, and d p
-
- Increase the dimension by one more and the situation gets
- quite hairy, worsened by the fact that you cannot visualize
- the matrix.
-
- Can any kindly soul suggest a reference that gives the
- procedure to calculate the determinant of an n-th order
- matrix of dimension m ? A book reference would be more
- understandable than a journal paper.
-
- Thanks a bunch!
-
- Ramli.

- PS: I would appreciate your sending any response to
