You almost have it. As the error (and help) indicate, you need to follow 'TiffTags' with a structure when calling geotiffwrite. You can do it in-line, like this:
geotiffwrite('output.TIF',A,R,'GeoKeyDirectoryTag',info.GeoTIFFTags.GeoKeyDirectoryTag,'TiffTags',struct('Compression',Tiff.Compression.None))
or you can first create a TIFF tags structure, like this, for example:
tags.Compression = Tiff.Compression.None;
geotiffwrite('output.TIF',A,R,'GeoKeyDirectoryTag',info.GeoTIFFTags.GeoKeyDirectoryTag,'TiffTags',tags)
In this case, tags has only one field. But you can add others, such as RowsPerStrip, for example, as needed.
