1. Opens a Matrix editor window with the matrix of your choice (Opening matrices).
2. Mark the desired matrix values (Marking matrix data).
3. Right-click a highlighted value.
The context menu opens.
4. Select Arithmetic operations on marked section > Natural logarithm.
|
Note: If the Matrix editor window contains any negative values or zero, the function aborts. |
For each OD pair selected, the natural logarithm is taken to the base e (Eulerian number, e ≈ 2.71828183) of the original matrix value and will be saved with the matrix.
|
Tip: To logarithmize the values, you can enter the arithmetic operation of your choice directly, just as into the Quick view or lists. To do so, select the matrix values of your choice and enter the expression =log. |
