Calculates one or more function values of a given formula that contains multiple variables.
Values of the variables where this node calculates function values.
This input accepts the following data types:
For 1D array inputs, each array element represents the value of the corresponding variable in variables.
For 2D array inputs, the i th row of the array contains the fixed values of the i th variable of the n-dimensional function. The other dimension of the array marks the n-dimension points at which this node calculates function values.
n independent variables of the given formula. variables has a one-to-one relation with x values.
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 value(s) at x values
This output can return the following data types:
Algorithm for Calculating y value
If x values is a 1D array of double-precision, floating-point numbers, this node calculates y value using the following equation: y = f(x 1, x 2, ..., x n), where n is the number of independent variables in the given formula.
If x values is a 2D array of double-precision, floating-point numbers, this node calculates y values using the following equation:
y i = f(x 1i , x 2i , …, x n i )

The following table shows examples of the inputs and outputs of this node.
formula | x values | variables | y values |
---|---|---|---|
3*x1 + 4*x2 + x3^2 | [1, -1, 2] | [x1, x2, x3] | 3 |
[1, 0; -1, 4; 2, 1] | [3,17] |
