Hi, I have a structure AA.BB, which goes from AA.BB(1) to AA.BB(1000). I have for example a matrix "X" of size [1000x3], which I want to add to this structure, such that it becomes like this: AA.BB(1).X(1)AA.BB(2).X(1)...AA.BB(1000).X(1) I want the same for X(2) and X(3). Can this be done without using a loop, in which all entries of the matrix are individually placed in the structure? I dont want to use a loop at all. I know it may be easier to just keep the matrix "X", but I want to know if such a thing can be done. Thanks in advance for your help!
