Ex. 1: For loopΒΆ
In this example, you will learn how to use the Loop node to
loop over a range of values (from 0 to 9) and evaluate the function:
\(y = x^2\)
First, add a Loop node to the sheet. Make the node large by
clicking and dragging the resize handle in the bottom right corner so we can fit
node inside. Create two Tunnel
terminals on the left of the node and one on the right. Right-click the top-left
terminal and change it to an Indexed terminal. Do the same with the terminal
on the right. Your sheet should now look like this:
Next, add a math.Power node inside the Loop node.
Connect the top-left Tunnel terminal to the base terminal on the
Power node and the bottom-left Tunnel terminal to the exponent terminal
of the Power node. Finally, connect the result of the Power node
to the right Tunnel node.
Now that all the connections inside the loop are complete, add Range and
Float nodes to the left of the Loop node. Connect the
range terminal on the Range node to the top-left Tunnel terminal on
the Loop node. Connect the Float terminal to the
bottom-left Tunnel terminal on the Loop node. Change the
value of the Float node from 0 to 2.
Finally, to show the results of the loop, add a Plot node to the right of
the Loop node. Connect the right Tunnel terminal on the
Loop node to the y terminal on the Plot node. Run
the sheet by pressing the button.
