RE: [AMPL 6685] Displaying variables after optimization
Robert Fourer
By default the AMPL "display" statement arranges tables so that there are more rows than columns. If a "(tr)" appears in the display then AMPL has transposed the table, using the earlier index for the columns and the later index for the rows; you can suppress this transposition by setting something like
option display_transpose -10000;
where the negative number is larger than the difference between the numbers of rows and numbers of columns. If a "(tr)" does not appear then AMPL has used the earlier index for the rows and the later index for the columns; you can force a transposition similarly but with a positive value:
option display_transpose 10000;
For a three-dimensional array, AMPL's display statement chooses to "slice" on the index that has the fewest different values; this can also be overridden but it's hard for me to explain in the current situation because I do not know what the definition of X looked like.

Subject: [AMPL 6685] Displaying variables after optimization
I want to modify the display of variables after the optimization.
I have a set of variables X [N, N, V]. If I use the command "display X;" it gives me back X[V, *, *] (with the index of the rows as N and index of columns as N).
I wanto to change it in X[N, *, *] (with the index of the rows as V and index of columns as N). Is it possible?
Thanks
