Similar to the Formula Node function but with variables that can be entered on the front panel. Refer to Formula VIs in More Detail for more information on the differences between the Eval Formula Node VI and the Formula Node function. Details

formula is a string consisting of one or more formulas separated by semicolons. Each formula is built up by Variables Input on the right side of an equation and Variables Output on the left side. | ||||||

error in describes error conditions that occur before this VI or function runs.
The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. This VI or function runs normally only if no error occurs before this VI or function runs. If an error occurs while this VI or function runs, it runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node.

Output Values is a 1D array of numbers corresponding to Variables Output and formula. The numbers in Output Values represent the results. | ||||||

error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, it describes the error status that this VI or function produces.
Right-click the error out indicator on the front panel and select Explain Error from the shortcut menu for more information about the error.
