Like this?

% Sample data
Data = randn(100,10);

% Calculate median for each column
med = median(Data);

% Visualize the result
figure
boxplot(Data)
hold on
plot(med,'ro-')

If you don't have the original data, then you can get at the graphical object that is the median line using

h = findobj(gca,'Tag','Median');
[h.YData];

This will give duplicates of the value, because it is the y-coordinate of the endpoints of the line.

It depends on what types of file your data is stored.

If your data is stored in CSV or Excel file format, it would be easy to import your data.
