Evaluate y=f(x) (f(a,x) Linear Step) (G Dataflow)

Last Modified: March 15, 2017

Calculates the values of a 1D function given by the specified formula at equidistant points in an interval.

This node is similar to the Evaluate y=f(x) (Linear Step) node but with the ability to integrate parameters into the formula. To obtain more accurate output values, consider using the Evaluate y=f(x) (Optimal Step) node.

datatype_icon

number of points

Number of values of the independent variable used in the function calculation.

Default: 10

datatype_icon

formula

Function to calculate. The formula 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.

datatype_icon

start

Start value of the interval where this node starts calculating values.

Default: 0

datatype_icon

end

End value of the interval where this node stops calculating values.

Default: 1

datatype_icon

error in

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.

error in does not contain an error error in contains an error
If no error occurred before the node runs, the node begins execution normally.

If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

Default: No error

datatype_icon

parameters

Variables and their corresponding values in the parameters.

datatype_icon

variable

Name of the parameter that uses the conventions of the Parsing nodes.

Default: Empty string

datatype_icon

value

Value of variable.

Default: 0

datatype_icon

x values

Variable values used in the function calculation. The values are equally spaced from start to end.

datatype_icon

y values

Function values at the corresponding points in x values.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.
