Analyzes a string as a formula and produces two numeric arrays. These arrays can be used by the Eval Parsed Formula String VI.

Inputs/Outputs

  • cstr.png formula —

    formula is a string representing the formula. The formula can contain any number of valid variables.

  • cerrcodeclst.png error in (no error) —

    error in describes error conditions that occur before this node runs. This input provides standard error in functionality.

  • icclst.png Parsed Formula —

    Parsed Formula can be wired directly to the corresponding input of the Eval Parsed Formula String VI.

  • i2di32.png Table —

    Table is a 2D array with 3 columns. The first column contains a code that stands for the operator. The other two columns contain codes that stand for the operands.

  • i1ddbl.png Y Values —

    Y Values is a 1D array of numbers representing a storage of detected and analyzed numbers of formula.

  • ierrcodeclst.png error out —

    error out contains error information. This output provides standard error out functionality.

    • Usually, the Parse Formula String VI is used at the beginning of the calculation of function values. The Eval Parsed Formula String VI completes the calculation. This division works well if the analyzing process of the Parse Formula String VI finishes before the calculation processes. Keep this in mind for your own programming.
