IsGeneralized(M) returns true if the MultiSet M was created via a constructor call of the form MultiSet[generalized].

$M≔\mathrm{MultiSet}\left(a=2\,b=5\right)$

$M≔\left\{\left[a\,2\right]\,\left[b\,5\right]\right\}$

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

$\mathrm{false}$

$N≔\mathrm{MultiSet}\left[\mathrm{generalized}\right]\left(c=-3\,d=\frac{1}{2}\,e=3.14159\,f\right)$

$N≔\left\{\left[c\,\mathrm{-3}\right]\,\left[d\,\frac{1}{2}\right]\,\left[e\,3.14159\right]\,\left[f\,1\right]\right\}$

$\mathrm{IsGeneralized}\left(N\right)$

$\mathrm{true}$

The MultiSet/IsGeneralized command was introduced in Maple 2016.
