Owning Palette: 1D & 2D Evaluation VIs
Requires: Full Development System
Calculates the values of a function (f(t), g(t)), where t runs over an interval. Both components are given by Formulas. The t-values are chosen equidistantly in the interval.
To obtain more accurate output values, consider using the Eval X-Y(t) Optimal Step VI.

 |
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. The default is 0.0. |
|
end is the end point of the interval. The default is 1.0. |
 |
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 is the array of the values of the first component, r(phi)cos(phi). |
|
Y is the array of the values of the second component, r(phi)sin(phi). |
 |
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. |
The functions t*sin(t), sqrt((t)*cos(t)) describe a curve in the plane, with t ranging between (0, 12). The following illustration shows this curve.
