I need to code a1, a2, a3 = 0. any idea how to do this? I've read about deal, but it seems too long to code 19-20 "a" variables.

I've read about deal, but it seems too long to code 19-20 "a" variables.
The follow-up question would be, I need to input the blade section data from Excel to Matlab. For instance, r1 = 1.27, r2= 1.35 where r is the radius. I have to deal with 19 elements so the data will go up to r19= 5. any tips on how to do this? :)
Kind regards, Wesley

Use a vector instead:
a = zeros(1, 19);
Now your "a1" is a(1).
It is not clear what "input the blade section data from Excel to Matlab" exactly means. I assume an xlsread or tableread might solve the problem.

How about putting them into a vector?
% put them into a vector
r = [1.27 1.35 1.4 1.5 1.6 1.7 1.8 1.9 2.0 2.1 2.2 2.3 2.4 2.5 2.6 2.7 2.8 2.9 5];
% Access your variables via indexing like Stephen's suggestion.
r(1)
r(19)

It depends on where you want to do the bulk of the work (MATLAB or Excel). Excel has ranges (e.g. B1:B8) and you can do basic math on that. MATLAB has ways of importing data from a saved Excel workbook (see for example, xlsread and xlsinfo). Once you have it in MATLAB though, it's generally easy to work with. Good luck.
