7. Recursive Loop

<p><strong>Recursive Loop</strong></p><p>This workflow implements an example of a recursive loop using the <em>Recursive Loop Start</em> and <em>Recursive Loop End</em> nodes. A recursive loop can pass the current results to the next iteration through the second input port of the <em>Recursive Loop End</em> node. The loop ends after a pre-defined number of iterations or when it reaches a condition, both can be configured in the <em>Recursive Loop End</em> node. </p><p>In this workflow, we first generate fake data with 3 clusters over 2 coordinates (x,y). In each loop iteration, we then calculate x = x+1, where x is the Universe_0_0 column. The result, however, is the same as in the workflow "1. Counting Loop", as you can see in the <em>Scatter Plot</em>.</p>
