Abstract

The matrix inversion technique for the T-matrix method recently suggested by Petrov et al. [Opt. Lett. 32, 1168 (2007)] is not new. Their way of implementing the technique, in which Strassen’s matrix multiplication algorithm is not adopted, does not save computation time when the $LU$ factorization technique of matrix computation theory is used.
