WebThen the calculation becomes: $$-\text{trace}(\rho \log m (\rho)) = \text{NaN}.$$ The reason is, we have to define $0 \times \log (0)$ as $0$ instead of $\text{NaN}$ which is the default behavior of Matlab. Another way to calculate it is the following: As this density matrix is representing a pure state, it would have a diagonalization. WebDescription. Y = log (X) returns the natural logarithm ln (x) of each element in array X.
