Copy, paste and apply diagonal
Note: The diagonal of a matrix runs from top left to bottom right (FromZoneNo = ToZoneNo). In demand matrices the diagonal represents the trips within the cell. |
The functions Copy diagonal into clipboard and Paste diagonal from clipboard enable the exchange of diagonal values between two matrices. For example, you can set a matrix value outside the diagonal to zero by copying the diagonal, setting all matrix values to zero and reinserting the diagonal (User Manual: Copying and pasting matrix diagonal values).
The set diagonal function, in the Matrix editor window, offers the option of setting the values of the diagonal with a new value, with the matrix values remaining unchanged for all relations FromZoneNo ≠ ToZoneNo.
In the procedure sequence, you can set the values of a diagonal by using the OnlyActiveODPairs or If function in formulas.
