The log1p(M) function computes the scaled element-wise base-e logarithm of M. The result, R, is formed as R[i,j] = log1p(M[i,j]).

$\mathrm{with}\left(\mathrm{MTM}\right)\:$

$M≔\mathrm{Matrix}\left(\left[\left[0.3\,0.2\right]\,\left[0.1\,0.4\right]\right]\right)\:$

$\mathrm{log1p}\left(M\right)$

$\left[\begin{array}{cc}0.2623642645& 0.1823215568\\ 0.09531017980& 0.3364722366\end{array}\right]$

The MTM[log1p] command was introduced in Maple 2021.
