What is the limit of exp(-kM/T)???

Let M be a matrix:

$$\left(\begin{array}{cc}a & b \\c & d\end{array}\right)$$

where a,b,c and d are complex constants. Let k and T be positive real numbers. Is there a closed formula for this limit?

$$\begin{array}{c}\lim \\ T->0^{+}\end{array} \;\;\; e^{-kM/T}$$

Of course the answer will not depend on k, or T.
