function V = spapulstemat(model, doasFreqs, params)

%SPAPULSTEMAT Calculation of space-pulse (space-slow time) steering matrix.
%
%--------
%Synopsis:
%  V = spapulstemat({antenna, waveform}, {doas, freqs})
%
%Description:
%  Calculates the space-pulse (space-slow time) steering matrix for the
%  specified DOAs and frequencies.
%
%  This function is normally not called by the end user but
%  by the extension programmer that extends the toolbox DBT with new signal
%  processing methods etc.
%
%
%Output and Input:
%  V (CxMatrix): The calculated pulse steering matrix. The size is
%    (noPulses x noChan, noFreqs x noDoa), where noPulses is the number of
%    pulses, noChan is the number of antenna channels, noFreqs is the number
%    of frequencies and noDoa is the number of directions
%  antenna (AntDefT): The definition of the receiving antenna to use.
%  waveform (WaveformT): The waveform definition.
%  doas (Vector of DoaT): Directions to calculate the steering vectors at.
%  freqs (RealVectorT.'): Frequencies to calculate the steering vectors at [Hz].

%Notations:
%  Data type names are shown in parentheses and they start with a capital
%  letter and end with a capital T. Data type definitions can be found in [1]
%  or by "help dbtdata".
%  [D] = This parameter can be omitted and then a default value is used.
%  When the [D]-input parameter is not the last used in the call, it must be
%  given the value [], i.e. an empty matrix.
%  ... = There can be more parameters. They are explained under respective
%  metod or choice.
