NumberCompose

NumberCompose[{c1,…,cn},{u1,…,un}]

returns the quantity c1 u1+…+cn un.

Details

  • The basis {u1,…,un} is typically a list of nonincreasing positive numbers.
  • In NumberCompose[clist,ulist] the length of clist can be smaller than the length of ulist, and then clist is effectively padded with zeros on the left.
