%  Calling Sequence
%
%numberOfElements = lcaGetNelem(pvs)
%
%  Description
%
%   Retrieve the element count of a number of PVs. Note that this is not
%   necessarily the number of valid elements (e.g. the actual number of
%   values read from a device into a waveform) but the maximum number of
%   elements a PV can hold.
%
%  Parameters
%
%   pvs
%          Column vector (in matlab: m x 1 cell- matrix) of m strings.
%
%   numberOfElements
%          m x 1 column vector of the PV's number of elements (``array
%          dimension'').
