In Response To 'Re: Solving simple Matrix problems' --------- I'm not certain this is what you are looking for. If after reading this you can clarify your question then I'll try again. In[1]:= Simplify[{pi1==0.8*pi1+0.2*pi2, pi2==0.1*pi1+0.9*pi2}] Out[1]= {1. pi1==1. pi2,1. pi1==1. pi2} In[2]:= Solve[{pi1==0.8*pi1+0.2*pi2, pi2==0.1*pi1+0.9*pi2},{pi1,pi2}] From In[2]:= Solve::svars: Equations may not give solutions for all "solve" variables. More… Out[2]= {{pi1->0.+1. pi2}} In[3]:= Solve[{pi1==8/10*pi1+2/10*pi2, pi2==1/10*pi1+9/10*pi2},{pi1,pi2}] From In[3]:= Solve::svars: Equations may not give solutions for all "solve" variables. More… Out[3]= {{pi1->pi2}}
