Hadamard :: hadamardPower(List,ZZ)

hadamardPower(List,ZZ) -- computes the $r$-th Hadmard powers of a set points

Synopsis

Description

Give a set of points $L$, the $r$-th Hadamard power of $L$ is $r$-times Hadamard product of L to itself; $( L x\cdots x L)_{r-times}$

i1 : L={point{1,1,1/2},point{1,0,1},point{1,2,4}}
