Dear All,
I would like to ask why the zeroeth power of a matrix gives me a matrix of ones rather than the identity matrix:
Because ^0 gives you the zero-th power of the _elements_ of the matrix, not the matrix itself. A matrix of 0^0 is all 1s.
Similary, '*' multiplies the elements together, it doesn't do matrix multiplication. For that you need %*%.
There is no %^% operator for matrix exponentials.
