Hello everyone,
I am fairly new to MATLAB so please bare with me.
I have the time series of the S&P500 for 18 years and I would like to compute the concentration ratio of the index for each day (just a column vector). I know that I can use the function concentrationIndices from the MATLAB Risk Management tool which supports 7 measures one of which is the concentration ratio.
I am now wondering how to create the loop so I would get the concentration index for each trading day. I thought that I can use the for function but it doesnt really work:
n = 347
t = 4779
for m = 1:t
ci(m) = concentrationIndices(Data200018(m,:));
end
The error I get is:
Subscripting a table using linear indexing (one subscript) or multidimensional indexing
(three or more subscripts) is not supported. Use a row subscript and a variable subscript.
Can you please tell me what I am doing wrong?
Many thanks in advance!
Nadya
