making a geotiff file from a netcdf file

I tried to convert my netcdf file in to a tiff file. The code i typed in the command window is,

filename='S2B_20190418_L2W_AOI.nc'
ncdisp(filename)
longitude=ncread(filename,'lon')
latitude=ncread(filename,'lat')
surface_442=ncread(filename,'rhos_442')
longitude = double(longitude)
latitude = double(latitude)
surface_442 = double(surface_442)
R = georasterref('RasterSize',size(surface_442),'LatitudeLimits',[39.1072,39.1093],........
          'LongitudeLimits',[26.5640,26.5688]);
tiffile ='surface_442.tif'
geotiffwrite(tiffile,surface_442,R)

The last step generates an error of:

Error using tifflib

Unable to open TIFF file "surface_442.tif".

Error in Tiff (line 651)

obj.FileID = tifflib('open',filename,mode);

Error in geotiffwrite>writeGeoTiffFile (line 1482)

tiffObj = Tiff(filename, writeMode);

Error in geotiffwrite (line 271)

writeGeoTiffFile(filename, A, TiffTags, GeoTiffTags, rpcTag,

isClassicTIFF);

I am grateful if you can kindly help to figure this out.

What is size of surface_442?

Thank you very much for replying. It is 42 x 24.

@KSSV Okay I did it by including the size. Thank you so much for the clarification.
