Did you check the type (whos) and range of "i"?
It should be an integer, if your iteration starts at 1 then (i-1) would 
be zero, "i" should also be smaller than 2^31.

Assuming "i" is yielding valid iterators, did you check the type (whos) 
of Theta{i} and a{i}? Maybe they're not real but have some other type 
that doesn't allow matrix multiplication.
