Computing the Karcher mean of symmetric positive definite matrices [PDF]
Linear Algebra and Its Applications, 2013 We present and analyze an iterative method for approximating the Karcher mean of a set of $n\times n$ positive definite matrices $A_i$, $i=1,\ldots,k$, defined as the unique positive definite solution of the matrix equation $\sum_{i=1}^k \log(A_i^{-1}X)
