loop

Dear helpers

I have this problem. I want to make a linear combination a*A+(1-
a)*B where A and B are matrices. I want that a be incremented 
from 0 to 1 by 0.1 so I made a loop with for. The problem is 
that I want to keep the result in an object or list or 
something like that and then apply eigen decomposition to all 
of the resulting matrices

sapply(my.list,eigen)

the problem is that I don't know how to build that list in the 
loop. I tried several things but it doesn't work (in Matlab i 
can do it)

thanks
luis
