Hello best helpers,

I am a new user and I have been struggling for hours. So finally I decide to ask you:
If I have a matrix P, and P.2 = P%*%P, and P.3=P.2%*%P
is there a function to calculate the power of a matrix?? if not how can i do:
for (i in 1:10)  {P.i=P^i} 
after this I need to sum them up and my problem is to combine P and i to P.i  can anyone help me please???

Thanks and have a nice day, 

Pascal.
