# MATLAB: Read specific 2D matrix from 3D matrix variable from netCDF….

Hi I have a netCDF file. I can access all its dimensions, variables etc in MATLAB using netCDF library. In the variables there is a variable whose size is mXnXp. Using the command:
data = netcdf.getVar(ncid,varid) ;
I can get the whole mXnXp variable, which is a 3D matrix. Here comes the problem, I dont want to access the whole variable, instead I want to access a 2D matrix mXn at a given number r = 1….p. Is there any command for this?
data = netcdf.getVar(ncid,varid,[1,1,r],[m n 1]);
data = ncread(netcdfFilename,varName,[1,1,r],[m n 1]);
