function dot = vecdot(vec1,vec2)
% 
% VECDOT: The dot product of two vectors.
% 
% Calling Sequence:
% 
%   dot = vecdot(vec1,vec2);
% 
% Parameters:
% 
%   vec1    : An array of column vectors represented by a matrix of
%   vec2    size (dim,nv), where is the dimension of the vector and
%           nv the number of vectors.
% 
%   dot           : Row vector of scalars, each element corresponding to
%           the dot product of the respective components in vec1 and
%           vec2.
% 
% Description:
% 
%   Scalar dot product of two vectors.
% 
% Examples:
% 
%   Determine the dot product of
%   (2.3,3.4,5.6) and (1.2,4.5,1.2)
%   (5.1,0.0,2.3) and (2.5,3.2,4.0)
%
%   dot = vecdot([2.3 5.1; 3.4 0.0; 5.6 2.3],);
