From The Free On-line Dictionary of Computing (27 SEP 03) [foldoc]:

  interpolation
       
           A mathematical procedure which
          estimates values of a {function} at positions between listed
          or given values.  Interpolation works by fitting a "curve"
          (i.e. a function) to two or more given points and then
          applying this function to the required input.  Example uses
          are calculating {trigonometric functions} from tables and
          audio waveform sythesis.
       
          The simplest form of interpolation is where a function, f(x),
          is estimated by drawing a straight line ("linear
          interpolation") between the nearest given points on either
          side of the required input value:
       
          	f(x) ~ f(x1) + (f(x2) - f(x1))(x-x1)/(x2 - x1)
       
          There are many variations using more than two points or higher
          degree {polynomial} functions.  The technique can also be
          extended to functions of more than one input.
