Find on the palette

	formula is a string representing the formula of n independent Variables. The formula can contain any number of valid variables.
	X Values is an array of x values corresponding to the n Variables.
	Variables is an array of strings representing the n independent variables of the given formula. There is a one-to-one relation between Variables and X Values.
	error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
	y value is the value of formula(X Values).
	error out contains error information. This output provides standard error out functionality.

Eval Multi-Variable Scalar Details

The VI calculates the function using the following equation.

y = f(x₁, x₂, …, x_n)

The following inputs result in y value 3.00:

• formula: 3*x1 + 4*x2 + x3^2
• X Values: [1, -1, 2]
• Variables: [x1, x2, x3]

Note  This VI calculates only one value of a given n dimension function. To calculate a collection of function values, use the Eval Multi-Variable Array, Parse Formula String, and Eval Parsed Formula String VIs.
