% This example shows how you can estimate kinematic
% variables from MoCap data and visualize them
%
% Time derivatives of motion-capture data can be estimated
% using the mctimeder function:
d2v = mctimeder(dance2, 1); % velocity
d2a = mctimeder(dance2, 2); % acceleration

pause %%%%%%%%%%% hit a key to continue %%%%%%%%%%%%%%%%%%%%%%%%%%

% Let us have a look at the vertical velocity component
% of markers 1, 19, and 25 (head, hand, and foot)

figure, set(gcf,'Position',[40 200 560 420])
mcplottimeseries(d2v, [1 19 25], 'dim', 3)

pause %%%%%%%%%%% hit a key to continue %%%%%%%%%%%%%%%%%%%%%%%%%%

% Next, let us plot the vertical acceleration components
% of the same markers

% The phase plane plot for velocity and acceleration can be
% produced as follows

% Here is the same phase plane plot, but for the interval

% The cumulative distance tavelled by a marker can be calculated
% with the function mccumdist
