Several matrix inverse properties

  1. Nov 1, 2012 #1

    I'm specifically trying to compute (VΔYT)-1, where V is nxn and orthogonal, Δ is diagonal, and Y is nonsingular.

    In general we have (AB)-1 = B-1A-1

    But how do we do this in general for many matrices? Is there a method, and as long as the matrix dimensions agreed, does the structure (i.e. orthogonal, nonsingular, SPD, etc) matter when computing the inverse of multiple matrices?

    I can't find this anywhere on the internet.
