nanm (Mapping Toolbox)

Create matrix maps of NaNs

Syntax

map = nanm(latlim,lonlim,scale)
[map,maplegend] = nanm(latlim,lonlim,scale)

Description

map = nanm(latlim,lonlim,scale) returns a regular matrix map consisting entirely of NaNs. The two-element vectors latlim and lonlim define the latitude and longitude limits of the geographic region. They should be of the form [north south] and [east west], respectively. The number of rows and columns per angle unit is set by the scalar value scale.

[map,maplegend] = nanm(latlim,lonlim,scale) returns the three-element map legend vector for the returned map.

Examples

[map,maplegend] = nanm([46,51],[-79,-75],1)
map =
   NaN   NaN   NaN   NaN
   NaN   NaN   NaN   NaN
   NaN   NaN   NaN   NaN
   NaN   NaN   NaN   NaN
   NaN   NaN   NaN   NaN
maplegend =
     1    51   -79
