1. (All students!) For matrices with special properties, it is possible to create special versions of Gauss elimination. Suppose matrix A (nxn) is symmetric (which means that A-A). Suppose also that A is positive definite; this means that the scalar = xTAx is always 20 for every vector x , and J-0 o...
