WIP, Description in progress
Two basic lemmas treat the elimination of variables in a partitioned matrix.
Lemma 1[edit | edit source]
Consider the matricies , , be symmetrix. Then, there exists a symmetric matrix such that
if and only if
.
Lemma 2[edit | edit source]
Let , , be given matrices of appropriate dimensions. Then there exists a matrix such that
if and only if
,
In this case, is given by
.
