Hello,

I have the following code:

D11=A1(1:1000,:)
D12=A1(1:2000,:)
D13=A1(1:3000,:)
D14=A1(1:4000,:)
D21=B1(1:1000,:)
D22=B1(1:2000,:)
D23=B1(1:3000,:)
D24=B1(1:4000,:)
D31=C1(1:1000,:)
D32=C1(1:2000,:)
D33=C1(1:3000,:)
D34=C1(1:4000,:)

I would like to fill new variables with a certain range of other 2D arrays. I know it's much better to use a "For" cycle, but I don't know how to do it properly with ranges. I kindly ask your help.

I thank you in advance,

Best regards,

It is not clear to me, what the inputs are and what you want to solve with the loop.

But hiding indices in thenames of variables is a shot in your knee. Use D{1,1}, D{1,2}, ... instead. The same for A1,B1,C1. As soon as you use arrays and indices, it is easy to call this inside loops.
