zerom (Mapping Toolbox)

Create a matrix maps of zeros

Syntax

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

Description

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

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

Examples

[map,maplegend] = zerom([46,51],[-79,-75],1)
map =
     0     0     0     0
     0     0     0     0
     0     0     0     0
     0     0     0     0
     0     0     0     0
maplegend =
     1    51   -79
