In MATLAB's box plot, is the calculation of the median including outliers? or just including only data between upper whiskers and lower whiskers?

If outliers are not considered, how to include outliers inside whiskers so that they are involved in the calculation of the median?

Let's do a test to try to figure it out:
rng(2);
data = randn(1,10);
figure();
plot(data)
med = median(data);
med_no_outlier = median(data(data > min(data)));
figure();
yline(med,'--g');
hold on
yline(med_no_outlier,'--m');
boxplot(data);
The median line from boxplot() matches the median calculated using all the data, so it looks like boxplot() uses all the data to compute the median.
