limitm

Determine latitude and longitude limits of a regular matrix map

Syntax

• [latlimits,lonlimits] = limitm(map,maplegend)
  limvec = limitm(map,maplegend)
  

Description

[latlimits,lonlimits] = limitm(map,maplegend) returns two-element limit vectors, latlimits and lonlimits, describing the extremes of the input regular matrix map with a legend vector maplegend.

latlimits and lonlimits are of the form [south-limit north-limit] and [west-limit east-limit], respectively. All elements are in degrees, since this command deals only with regular matrix maps.

limvec = limitm(map,maplegend) returns a single, four-element output vector of the form: [south-limit north-limit west-limit east-limit].

Examples

Using a familiar matrix map:

• load topo
  [latlimits,lonlimits] = limitm(topo,topolegend)
  latlimits =
     -90    90
  lonlimits =
       0   360
  

Which is what we expect, since topo covers the whole globe.
