any option as applying while code to develop pipeline connection within looped network; has noted zero indexing

any assistance, please. the attached excel might be useful.

In general, am duplicating connection of pipeline head losses in Water Distribution Network (WDN), looping. Data1_8= [3; 5; 7; 8; 2; ...100] with 34 datasets. it seem matr1(2:3,6:7) is challenging one as need zero indecing in while loop; meanwhile the while responding after testing the condition, this main challenge of course

Thank indeed

The code you posted is not readable. Confusing and not indented and not formatted as code. Please fix it so we can read it.

else(matr1(rL,3)==11);

I suspect from context that you wanted

elseif(matr1(rL,3)==11);
