[Gretl-users] Re: Reverse a cross tabulation or frequency table

On the other hand, Sven's remark made me think that sometimes you might want to compute all possible indices of a arbitrarily-sized tensor. Once you have those, you can use them in a single loop without having to nest many. The function is: ... So for example, you can create X = indices({2,3}), which would yield   1   1   1   2   1   3   2   1   2   2   2   3 ... The nice thing is, the number of elements in the argument to the "indices" function is potentially unlimited. For example, indices({3,2,3}) returns   1   1   1   1   1   2   1   1   3   1   2   1   1   2   2   1   2   3   2   1   1   2   1   2   2   1   3   2   2   1   2   2   2   2   2   3   3   1   1   3   1   2   3   1   3   3   2   1   3   2   2   3   2   3 Maybe we could add this to the extra addon?
