% INPUT
% matrix  matrix of data plotted
% x      coordinates associared with columns
% y      coordinates associated with rows
% xinfo  info about x-coordinates; horizontal (optional)
% yinfo  info about y-coordinates; vertical (optional)
% zinfo  info about z-coordinates; values of matrix (optional)
% bool   logicl variable; if "bool" is true then menu button will be created
%        Default: bool=logical(1);
% axis_handle   handle of axis that should be tracked
