A pairwise matrix is typically used to evaluate priority or to measure the strength of a relationship between row and column values. In Workspace, you set up a pairwise matrix by creating a data-entry table that has the same variable in both the row and column.
When you choose to make cross-diagonal cells the same in a pairwise matrix, Workspace
automatically copies the value entered by the user to the corresponding cross-diagonal cell. This is useful for sorting when the copied values in the pairwise matrix are hidden by conditional formatting, as shown in the following image.
