function[M]=splitbeamtracker_plotcoordinatesystem(ZZ,par,scale)
% Plot the platform state matrix as a function of time
%
% Optional input:
% ZZ : [pingnumber time x' y' z' theta phi psi]
% [.......... .... .. .. .. ..... ... ...]
% [.......... .... .. .. .. ..... ... ...], where:
% Pingnumber : index for the time
% Time : Time in matlab format
% x' y' z' : The position of the platform in ENU coordinates
% theta : Pitch (rotation around the platform's original y-axis)
% phi : Roll (rotation around the platform's original x-axis)
% psi : Compass reading
% par : The tracker parameter structure (to determine the
% direction and position of the acoustic axis relative to
% the platform), where
% par.transducerrot : A rotation matrix for the acoustic beam
% par.transducerpos : Position of the transducer relative to the platform
% scale : Scale the plot to fit the data (yet to be implemented)
%
% Note 1 : All angles are in radians
% Note 2 : Positive rotation follow the right hand rule. Take your
% right hand and point the thumb along e.g. the
% x-axis. "Close" your fingers and the fingertips will
% point along the positive rotation.
% Note 3 : The angles input are the "real" tilt and roll angles. If
% large tilt angles are used, discrepancies in the
% platform coordinate system occurs because of the order
% of the rotations, i.e. first along the x-axis and the
% along the y-axis
%
% Note 4 : The green part of the acoustic beam indicate starboard
% in the transducer coordinate system

function H=arrow3(p1,p2,s,w,h,ip)
% ARROW3
% ARROW3(P1,P2) will draw vector lines (2D/3D) from P1 to P2 with
% arrowheads, where P1 and P2 can be either nx2 matrices (for 2D),
% or nx3 matrices (for 3D).
%
% ARROW3(P1,P2,S,W,H,IP) can be used to specify properties of the
% line and arrowhead. S is a character string made with one element
% from any or all of the following 3 columns:
%
% Color Switches LineStyle LineWidth
% ------------------- ------------------- --------------------
% k black (default) - solid (default) 0.5 points (default)
% y yellow : dotted 0 no lines
% m magenta -. dashdot / LineWidthOrder
% c cyan -- dashed
% r red * LineStyleOrder
% g green
% b blue
% w white
% x random named color
% o ColorOrder
%
% LineWidth units are points (1/72 inch); use 0 to omit lines.
% Invalid characters in S will be ignored and replaced by default
% settings. W is a vector of arrowhead widths. H (default = 3W) is
% a vector of arrowhead heights. If a value is provided for IP, an
% initial point marker will be plotted with width IP; use IP = 0 for
% default width W. For linear plots with equal axes, the units of W,
% H, and IP are the same as those of the coordinate data (P1,P2).
%
% Note that MATLAB cycles through the line styles defined by the
% LineStyleOrder property only after using all colors defined by
% the ColorOrder property. If however, the global variable
% LineWidthOrder is defined, and LineWidth is specified with '/',
% then each line will be drawn with sequential color, linestyle,
% and linewidth.
%
% Plotting lines with a single color, linestyle, and linewidth is
% faster than plotting lines with multiple colors and/or linestyles.
% Plotting lines with multiple linewidths is slower still.
%
% If a particular aspect ratio is required, use DASPECT or PBASPECT
% before calling ARROW3. Changing DASPECT or PBASPECT after calling
% ARROW3 may change the appearance of arrowheads and initial point
% markers. Arrow3 sets DataAspectRatioMode to manual for linear
% plots and sets PlotBoxAspectRatioMode to manual for log plots.
