Ranking Random Numbers

[djp004]

I am trying to assign a random number to a constant value and then rank the assigned random number in ascending or descending order then use the ordered sequence of random numbers to execute a random run pattern for a multiple sequence case structure.

For example the constants would start with zero and continue trough ten in increments of 1. A random number needs to be associated with each constant and then the random numbers that are assigned placed in descending or ascending order. After that they are to be used to execute specific frames in a sequence case structure.

If I understand you right, you want to simply shuffle an array of numbers in random order.

The attached example (LabVIEW 7.0) will do that for you.
(It is important to know that arrays of clusters are sorted by the first cluster element).

Note that newer LabVIEW versions have the riffle function, which does the same in one step. 🙂
