Remove discontinuities in longitudes
Syntax
ang = smoothlong(angin) ang = smoothlong(angin,units)
Description
ang = smoothlong(angin) removes discontinuities in longitude data. The resulting angles may cover more than one revolution. ang = smoothlong(angin,units) removes
mat = spcread(cols) uses the units defined by the input string units. If omitted, default units of 'degrees' are assumed.
Examples
long = npi2pi(0:10:720); long2 = smoothlong(long); figure;hold on plot(long,'--'); plot(long2) xlabel 'Point Number'; ylabel Longitude
Remarks
This function can remove large jumps in longitude that might otherwise result in spurious data when interpolating withinterpm.
