Note that the link attribute must first be initialized to the desired (positive) color for all other links since links with a color index of 0 are not displayed.
5.3.2: Can temporary link attributes tmplx be used in selections?
No. However, it is possible to include conditions within the expression in order to "simulate" the selection. For example, if you want to change the length of the links only for those links having tmpl1 greater than 0, the expression would be:
It is also possible to replace temporary attributes by extra attributes, which can be used in the selections.
5.3.3: How can I write an expression that ensures a negative value is replaced by 0?
Use the .max. operator: (expression) .max.0.
5.3.4: In the network and matrix calculators, why are the results saved when I send the report to the printer but not when I send the report to the terminal?
Probably because you stopped the display of the report prematurely with a r or q. If you do not want to look at the remainder of the report, type l to skip to the end of the report.
5.4 Matrices
5.4.1: Why do some of my matrices have a "/c" flag?
Probably because a transit assignment did not end normally. During a transit assignment, matrices are transformed to columnwise format in order to work destination by destination. At the end of the assignment, the matrices are retransformed to rowwise format. If the transit assignment does not end normally, the matrices will stay columnwise. Since working with columnwise matrices will increase the matrix access time drastically, you should change the storage type of columnwise matrices by using Module 3.12, option 3 (modify a matrix).
5.4.2: Matrix calculations are very slow. Is there a way to speed this up?
You could do the following
