LONSHIFT Shifts longitude origin for plotting purposes. LON=LONSHIFT(LONO,LON) shifts the array LON such that its first point its just greater than LONO. This is used for controlling where the longitude break occurs on a map of the earth. LON may be given either on the interval [-180,+180] or on [0,360], and LONO may take on any value, e.g. -340, 20, 380, etc. [LON,X1,X2,...XN]=LONSHIFT(LONO,LON,X1,X2,...XN) also shifts the N matrices X1...XN. These matrices must be oriented such that their number of columns is the same as the length of LON. Upon output, LON will increase from a minimum value of LONO. 'lonshift --t' runs a test. Usage: lon=lonshift(lono,lon); [lon,x1,x2,x3]=lonshift(lono,lon,x1,x2,x3); __________________________________________________________________ This is part of JLAB --- type 'help jlab' for more information (C) 2007--2013 J.M.
