zerom

Construct regular data grid of 0s

zerom is not recommended and may be removed in a future release. Instead, use georefcells to construct a geographic raster reference object and then use zeros to initialize a data grid of the appropriate size:

R = georefcells(latlim,lonlim,1/scale,1/scale);
Z = zeros(R.RasterSize);

Syntax

[Z,refvec] = zerom(latlim,lonlim,scale)

Description

[Z,refvec] = zerom(latlim,lonlim,scale) returns a full regular data grid consisting entirely of 0s and a three-element referencing vector for the returned Z. 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 scalar scale specifies the number of rows and columns per degree of latitude and longitude.

Examples

[Z,refvec] = zerom([46,51],[-79,-75],1)

Z =
     0     0     0     0
     0     0     0     0
     0     0     0     0
     0     0     0     0
     0     0     0     0
refvec =
     1    51   -79
