Abstract: For Hadamard and conventional powering, we survey past and current work on the existence and values of critical exponents for such matrix classes as doubly nonnegative, totally positive, M- and inverse M-matrices. There are remarkable similarities and differences between Hadamard and conventional critical exponents for the various classes.
