I have a following piece of code and need to convert it using for loop.

[lnCorrectSub2Vid1] = lineCorrection(bScrnSub2_vid1.ecg, vid1{1,2}.ecg);
[lnCorrectSub2Vid2] = lineCorrection(bScrnSub2_vid2.ecg, vid2{1,2}.ecg);
[lnCorrectSub2Vid3] = lineCorrection(bScrnSub2_vid3.ecg, vid3{1,2}.ecg);
[lnCorrectSub2Vid4] = lineCorrection(bScrnSub2_vid4.ecg, vid4{1,2}.ecg);
[lnCorrectSub2Vid5] = lineCorrection(bScrnSub2_vid5.ecg, vid5{1,2}.ecg);
[lnCorrectSub2Vid6] = lineCorrection(bScrnSub2_vid6.ecg, vid6{1,2}.ecg);
[lnCorrectSub2Vid7] = lineCorrection(bScrnSub2_vid7.ecg, vid7{1,2}.ecg);
[lnCorrectSub2Vid8] = lineCorrection(bScrnSub2_vid8.ecg, vid8{1,2}.ecg);

I wrote following code using for loop (I want do something like this) but I do not know how to iterate through variable.

for jj = 1:8
    bslnCorrectSub2Vid(jj) = baselineCorrection(bScrnSub2_vid(jj).ecg, vid(jj){1,2}.ecg);
end

Can I iterate through variable or should I change variable naming?

You painted yourself in a corner by storing data in a variable name.

If you had used a cell array from the start, you could have used easy indexing.

The solution is to change how your data is created. Make sure not to rely on a variable name. Your entire code should still make sense if you rename a variable.
