Evaluates mathematical formulas and expressions with variables.
Equations to calculate, with output variables on the left and input variables on the right. If you have multiple equations to calculate, separate them with semicolons. The equations can contain any number of valid variables.
Entering Valid Variables
This node accepts variables that use the following format rule: variables must start with a letter or an underscore followed by any number of alphanumeric characters or underscores.
Values for the input variables that this node uses to calculate function values. input values has a one-to-one relation with variables input.
Input variables from the right side of the equations in formula.
Output variables from the left side of the equations in formula.
Error conditions that occur before this node runs.
The node responds to this input according to standard error behavior.
Standard Error Behavior
Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.
Default: No error
Function values of the output variables. output values has a one-to-one relation with variables output.
Error information.
The node produces this output according to standard error behavior.

The following table shows an example of the inputs and outputs of this node.
formula | input values | variables input | variables output | output values |
---|---|---|---|---|
y = 3*x + 4*z; p = q^2 - 5 | [1, 2, 3] | [x, z, q] | [y, p] | [11.00, 4.00] |
