> Produce multiple sets of acceleration coefficents from a waveform

> Calculate specified types of acceleration coefficients. This function is used when the base types of coefficient haven't been calculated. This function calls sig2coef to calculate the base types from which the deltas are calculated, and hence the requirements governing the setup of <parameter>fv</parameter> for sig2coef also hold here.

Parameters:
  sig - : input waveform
  fv - : output coefficients. These have been pre-allocated and the number of channels in a indicates the order of the analysis.
  op - : Features structure containing options for analysis order, frame shift etc.
  slist - : list of types of acceleration coefficients required. The delta function is used to produce a set of coefficients which estimate the rate of change of a set of parameters.
