directionavg#

[diravg] = directionavg(direction, NPointsAvg, NPointsInterval, dispout)

Description#

Average direction

Inputs#

direction: Direction time series data in (degree)
NPointsAvg=length(direction(:,1));: Number of data points from start of each section (interval) to be averaged
NPointsInterval=length(direction(:,1));: Number of points that each section (interval) has
dispout=’no’;: Define to display outputs or not (‘yes’: display, ‘no’: not display)

Outputs#

diravg: Averaged direction data in (degree)

Examples#

direction(:,1)=45.*rand(10,1);
[diravg]=directionavg(direction);

direction(:,1)=225.*rand(5*60,1); %One data point every minute for 5 hours
[diravg]=directionavg(direction,10,60,'yes');
