Two Dimensional GDOP

GDOP Psuedocolor Values and Plot

Description

gdopContour shows a psuedocolor image of the PDOP (GDOP in 2-D is referred to as PDOP). xmin/xmax/ymin/ymax are the limits on the plot. SVs is an [x,y] matrix showing the position of the "Space Vehicles" (GPS terminology). You can have unlimited SVs. The returned value is the PDOP matrix over the input window.
