Input:
for j=1:NS
tsr(j)=((r(j)*rot)/v); %TSR
end
For loop iteration
X(j) requires tsr(j) and a(j).
Both X(j) and a(j) changes every loop.
Before, I use X1(i-1), X2 (i-1).
After receiving suggestions from this forum to use indexing instead, I revised the code using indexing (still a newbie ^^,)
Any idea on how to approach this? It seems I have to deal with X(j,i-1) where j, indexes to 20 variables (equal to X1,X2, X20) and i has something to do with iteration.
Kind regards,
Wes

I followed that sir! the next problem is the indexing and the iteration part. since the variables within the iteration loop have to be indexed as well, hence the confusion.

for instance, phi is within the iteration loop. instead of phi1(i-1), phi2(i-1), phi has to be indexed. the problem now moves on to the iteration procedure. could I use two for loops? I'm wondering what will be their respective index will look like.
