Matlab中的数据集

Question

I have a large set of cross-sectional time series data in a dataset in Matlab and I want to extract arrays (columns) of data based on the header which will be given dynamically from another array in for loop. Can anyone suggest how to implement this in Matlab, I have tried the following code

cdslist = universe.Bond;
cdscount = length(universe.Bond);

for i=1:cdscount
    cds = cdslist(i);
% here i want to use this variable cds to dynamically give names to a dataset called spread, for instance spread.cds where cds is changing in the loop. 

end

Is this possible ? Thanks for the help

Answer 1

Assuming cds is a string, it can be used as a dynamic field name:

cdslist = universe.Bond;
cdscount = length(universe.Bond);

spread = struct;

for i = 1:cdscount
    cds = cdslist{i};
    spread.(cds) = data;
end
