MATLAB: Create a new row in a loop

row

Please forgive me if this is a basic question. I would like to create a new row as the value for freq increases by one to the struct coherence that is created.
for freq = 10; % Would change to freq=10:50
coherence = {};
for coherence_index = 1:length(three_d_trials)
coherence{coherence_index} = cmc_coherence(three_d_trials{coherence_index}, freq, 1000);
coherence{coherence_index} = squeeze(coherence{coherence_index});
end
end

Best Answer

f1=10; f2=50;
coherence=cell(numel(f1:f2),numel(three_d_trials));
j=0;
for freq=f1:f2
j=j+1;
for coherence_index = 1:length(three_d_trials)
coherence{j,coherence_index} = squeeze(cmc_coherence(three_d_trials{coherence_index}, freq, 1000));
end
end
What's the squeeze for???
