function [xis] = EDB1findis(xsou,ivec,planeeqs,nsou,onesvec)
% EDB1findis - Returns the image source coordinates
% Returns the image source coordinates
% via mirroring one or N sources in a list of planes.
%
% Input parameters:
%   xsou		Matrix, [N,3], of the source coordinates.
%   ivec		List, [nplanes,1], of plane numbers that the source
%               should be mirrored in. If N ~= 1, then nplanes must
%               be = N.
%   planeeqs	Matrix [nplanes,4] of the plane equations.
%   nsou        The value N.
%   onesvec     A list that should be = [1 1 1].
%
% Output paramaters:
%   xis			Matrix [N,3] of all image sources to the source(s)
%               via all the planes specified in ivec and planeeqs.
%
% Uses no special functions
