Hi,
try something similar to the following or check my post in the same thread:
http://thread.gmane.org/gmane.comp.lib.boost.ublas/3546/focus=3551
and substitute return std::abs(t) for your own function. Don't forget to
rename the operator. I wouldn't call it sqrt(matrix) though, but instead
sqrt_element(matrix), as Gunter suggested.
