nrCDLchannel usage in "NR PDSCH Throughput" Example

Hi at all,

I'm using the NR PDSCH Throughput example and I have a doubt about the nrCDLchannel object usage. In particular I don't understand how the Tx antenna pattern is take into account and if there is any way to modify the pattern according to an external antenna pattern file.

Thank you

        % Pass data through channel model. Append zeros at the end of the
        % transmitted waveform to flush channel content. These zeros take
        % into account any delay introduced in the channel. This is a mix
        % of multipath delay and implementation delay. This value may
        % change depending on the sampling rate, delay profile and delay
        % spread
        txWaveform = [txWaveform; zeros(maxChDelay, size(txWaveform,2))];
        [rxWaveform,pathGains,sampleTimes] = channel(txWaveform);
