I've been using LinearSolve in Mathematica to get a solution for a Markov probability system where the coefficients range over 6 magnitudes. A colleague is trying to use CalculationCenter to run my notebook. Unfortunately CalculationCenter doesn't have LinearSolve, so we've been trying to get a solution using Det. The naive approach using Det[matrix with reduced column]/Det[matrix] for each column in turn isn't able to get a solution - well, it bunches the probability mass in two states. are there alternative approaches in CalculationCenter; presumable LinearSolve's multiple methods solution techniques are able to cope with a system where a naive approach doesn't work. thanks, Eric
