5 Data Analysis
The extent of the smoothing is controlled with the variable span.The
averaging calculation returns
NaN values whenever the smoothing window
includes the
NaN value in the data, thus increasing the size of the gap in the
smoothed data.
The MATLAB
filter function is also used for smoothing data:
smoothed2_c3m = filter(window,1,c 3m);
delete(h)
plot(smoothed2_c3m,'ro-');
