DetailsDetails

  • Ratios divides successive elements by preceding ones, so that Ratios[{x1,x2}] gives .
  • If list has length s, Ratios[list,n] has length .
  • Ratios[m,{1,0}] or Ratios[m,1] finds the successive ratios of rows in a 2D array or matrix m. Ratios[m,{0,1}] finds the ratios of columns.
  • Ratios[list,{n1,n2}] is equivalent to Ratios[Ratios[list,n1],{0,n2}].
