If I have a 2 data columns and I want to raise them to the power of K and sum the using sigma notation from k=1 to 10 how would I do that. So far I have tried.
Datacolumn1; %defined variables
Datacolumn2;
f=0;
for k=1:10
Data=(Datacolumn1.^k-Datacolumn2.^k).^2; %I want datacolumn1.^k minus datacolumn2.^k all squared summed(sigma notation) from k=1:10
f=f+Data
end
Have I entered that correctly. Any help would be appreciated.

k=?? % define
Data=Datacolumn1.^k+Datacolumn2.^k;
result=sum(Data(1:10));
If your code is correct? then
k=?? % define
Data=(Datacolumn1.^k-Datacolumn2.^k).^2;
result=sum(Data(1:10));

Is this?
k=?? % define
Data=(Datacolumn1.^k-Datacolumn2.^k).^2;
result=sum(Data(end-9:end));

Hi there would I not need a for loop as k starts at 1 and goes to 10 for sigma. I think its just the root mean square error with k powering the vectors.
