Hello!

I am trying to take the median values of all of the columns within a 16000x171 table but received errors despite trying varfun, splittapply, median itself, etc. How would I go about taking the median or applying functions to all of the columns in the table?

Thank you for the help!

Maybe you are searching for this?

A = (1:10)'
B = (11:20)'
T = table(A,B)
func = @median
M = varfun(func,T)

Thanks! I'll try this as well!

Try this:

% Create sample data.
col1 = rand(160, 1);
col2 = rand(160, 1);
t = table(col1, col2)
% Convert table to matrix.
m = table2array(t);
% Get median over rows in each column
columnMedians = median(m, 1)
