netcdf.getVar vs ncread

Question

The following command works:

ncread(ncfile,'some_variable',[1 1],[Inf 1]);  % assuming ncfile is a netcdf file that exists and has the variable listed

It reads in an array as the 'Inf' value instructs Matlab to read all values along the first dimension.

The command below, however, fails:

netcdf.getVar(ncid,some_variable_id,[1 1],[Inf 1]) % ncid is the ID of ncfile (see previous line of code)

and I get an error message stating "Index arguments must be finite." How then does one use netcdf.getVar to read all values along a dimension?

PS: I have deleted an earlier related question that had some errors.

You fetch the information about the variable and substitute in the known size instead of inf .

Thanks! I just decided to use ncread instead.
