Hi there,
I have a massive table with 408 columns in MATLAB. I want to get rid of columns that start with the word "connected". Instead of having to manually check the table and do something like
finalnbs(:,212:364) = [];
Where
finalnbs
is the table, how do I find all columns in finalnbs which start with connected e.g.
connected*
And then remove those?

finalnbs(:,strncmp(finalnbs.Properties.VariableNames, 'connected', length('connected')) ) = [];

Hello
if "titles" is the first row of your table, then:
titles = finalnbs(1,:);
%Select the columns that should stay
idxs = cellfun(@(x) length(x) < 9 || ~strcmp(x(1:9),'connected'),titles);
finalnbs = finalnbs(:,idxs);

Hello,
I have a similar problem but in my case I would like to remove the columns which contain the word "free".
How can I do that?
Thanks!
Joseba
