what is the meaning of this colon？and this sentence quant_set(i,:) = [ink(1,2*(i-1)+1) q05(i) q95(i)];

x_ink = data_rampe(101,18)/s; for i = 1:designs name(i,1) = data(1,1); set_data(:,1) = data(1:101,18); set_data(:,2) = data(1:101,19); % Inkremente herausschneiden und in ink abspeichern for n = 1:s a = find(set_data(:,1)>=(x_ink*n),1,'first'); ink(i,2*(n-1)+1) = set_data(a,1); ink(i,2*n) = set_data(a,2); ink_x(i,n) = set_data(a,1); ink_y(i,n) = set_data(a,2); end % Reduziert die Datenmenge um ein Design data(1:101,:) = []; end %% Bestimmung der 5 - 95 % - Werte for i = 1:s q05(i) = quantile(ink(:,2*i),y_low); q95(i) = quantile(ink(:,2*i),y_up); quant_set(i,:) = [ink(1,2*(i-1)+1) q05(i) q95(i)]; end

The assignment:

quant_set(i,:) = [ink(1,2*(i-1)+1) q05(i) q95(i)];

creates a (1x3) row vector for row ‘i’ of the ‘quant_set’ matrix with the designated elements. The colon operator ‘:’ could be replaced by ‘quant_set(i,1:3)’. The default colon operator ‘:’ is easier, especially if the programmer wants to change the number of columns as the script may require as it is developed.
