MultiSet/*

MultiSet * operator

 Calling Sequence m * M

Parameters

 m - integer; a real number, which must be a positive integer unless M is generalized, in which case it must be nonzero M - MultiSet; a MultiSet

Description

 • m * M returns the MultiSet whose elements are the elements of M and whose multiplicities are m times the corresponding multiplicities in M.

Examples

 > $M≔\mathrm{MultiSet}\left(a=2,b=5,c=4\right)$
 ${M}{≔}\left\{\left[{a}{,}{2}\right]{,}\left[{b}{,}{5}\right]{,}\left[{c}{,}{4}\right]\right\}$ (1)
 > $3M$
 $\left\{\left[{a}{,}{6}\right]{,}\left[{b}{,}{15}\right]{,}\left[{c}{,}{12}\right]\right\}$ (2)
 > $N≔\mathrm{MultiSet}\left[\mathrm{generalized}\right]\left(x=1.5,y=-\frac{1}{2}\right)$
 ${N}{≔}\left\{\left[{x}{,}{1.5}\right]{,}\left[{y}{,}{-}\frac{{1}}{{2}}\right]\right\}$ (3)
 > $\frac{3}{2}N$
 $\left\{\left[{x}{,}{2.250000000}\right]{,}\left[{y}{,}{-}\frac{{3}}{{4}}\right]\right\}$ (4)

Compatibility

 • The MultiSet/* operator was introduced in Maple 2016.
