Hello,

I am trying to split my table at ceratin rows. I have several Data sets, so the row numbers are not always the same. I have stored the rows where the table should split in an array. If, for example, my array is [500 900 1200], then I want the table to be split as following:

T1=row 1-499

T2=row 500-899

T3=row 900-1199

T4=row 1200-end

I have tried doing this with a for loop for the middle section (T2, T3) but this returns the table together and not split. Any ideas? :)

% array with the rows where the table should be split is Split_Rows
for a=length(Split_Rows)-1
        k=Split_Rows;
        SplitTable=FlowData([k:k(a+1)-1],:);
        
       
    end

Using numbered variables is a sign that you are doing something wrong.

Rather than using numbered variables, you should use simple and efficient indexing, exactly as madhan ravi's answer shows.

v=[1 500 900 1200]; 
 % ^--appended 1 at the beginning
Splittable=cell(numel(v)-1,1);
for k=2:numel(v)
    Splittable{k-1}=T(v(k-1):v(k)-1,:);
end
Splittable{k}=T(v(end):end,:) % where T is your table
