MATLAB: Extracting the median of a boxplot

From the documentation:

boxplot creates a visual representation of the data, but does not return numeric values. To calculate the relevant summary statistics for the sample data, use the following functions: {In the documentation, the function list follows}

So, to get the median of the first box in a particular plot, do something like this:

Data = randn(100, 10);
Median_1 = median(Data(:,1));
figure(1)
boxplot(Data);
grid

MATLAB: Divide data and take the median

If you want to take the median of ‘b(1:20)’, ‘b(21:40)’..., this works:

med_b = median(reshape(b(:), 20, []));
