Hm, then I somewhere must have an error in my computation.

I wanted to compute the Matrix logarithm via the formula

.

For A being the power derivation matrix of at 0, i.e. truncated to 6x6

(which is transposed to the matrix you usually uses).

This Matrix is diagonalizable, but if I compute the logarithm via the above sum then the entries do not converge. For example:
