With the cursor, grab the bottom middle selector of the array and drag it down to show multiple elements. Complete the following steps to create a VI that computes different formulas depending on whether the product of the inputs is positive or negative. Notice, however, that the if statement does not require a semicolon after the first line. Repeat steps 3 and 4 to add another input and label it y. You changed your response to Helpful. Your block diagram should appear as follows. Enters tan into the formula. Furthermore, you can copy and paste existing code directly into the Formula Node rather than recreating it graphically.

  • Jun 7, The Formula Node in the LabVIEW software is a convenient, text-based node you can use to perform complicated mathematical operations on a block diagram using the C++ syntax structure. LabVIEW MathScript is generally compatible with.m file script syntax, which is widely used by. Wow, what horrible LabVIEW code -- it even has a Stacked So I guess it's obvious how to use a vi instead of the formula string for the.
