Eval X-Y(a,t) VI

Owning Palette: 1D & 2D Evaluation VIs

Requires: Full Development System

Calculates the (x, y) coordinates of a curve by calculating the parametric function values of x = f(t) and y = g(t), where t runs over an interval.

	number of points is the number of all calculated points. The independent variable is split into equidistant subpoints. The default is 10.
	start is the start point of the interval under investigation. The default is 0.0.
	end is the end point of the interval. The default is 1.0.
	Parameters is an array of clusters describing the parameters. name of the parameter that uses the conventions of the Formula Parsing VIs. value is the user-defined value of the parameter.
	Formulas is an array of two strings describing the two function components f(t) and g(t). The formula can contain any number of valid variables.
	X returns the values of the x-coordinates of the curve. The values are obtained by calculating the function values of f(t) in Formulas.
	Y returns the values of the y-coordinates of the curve. The values are obtained by calculating the function values of g(t) in Formulas.
	ticks is the time in milliseconds to analyze the formula and to produce the X and the Y array.
	error returns any error or warning from the VI. You can wire error to the Error Cluster From Error Code VI to convert the error code or warning into an error cluster.
