`Vect1`

Name of the first vector that contains the noisy data set (i.e., independent variable). You must create and fill this vector before issuing

**EDNDTSD**.`Vect2`

Name of the second vector that contains the dependent set of data. Must be the same length as the first vector. You must create and fill this vector before issuing

**EDNDTSD**.`DATAP`

Number of data points to be fitted, starting from the beginning of the vector. If left blank, the entire vector will be fitted. The maximum number of data points is 100,000 (or greater, depending on the memory of the computer).

`FITPT`

Curve fitting order to be used as a smooth representation of the data. This number should be less than or equal to the number of data points. However, because high order polynomial curve fitting can cause numerical difficulties, a polynomial order less than 7 is suggested. The default (blank) is one-half the number of data points or 7, which ever is less. The following values are available:

**1**—

Curve is the absolute average of all of the data points.

**2**—

Curve is the least square average of all of the data points.

**3 or more**—

Curve is a polynomial of the order (n-1), where n is the number of data fitting order points.

`Vect3`

Name of the vector that contains the smoothed data of the independent variable. This vector should have a length equal to or greater than the number of smoothed data points. In batch (command) mode, you must create this vector before issuing the

**EDNDTSD**command. In interactive mode, the GUI automatically creates this vector (if it does not exist). If you do not specify a vector name, the GUI will name the vector smth_ind.`Vect4`

Name of the vector that contains the smoothed data of the dependent variable. This vector must be the same length as

. In batch (command) mode, you must create this vector before issuing the`Vect3`

**EDNDTSD**command. In interactive mode, the GUI automatically creates this vector (if it does not exist). If you do not specify a vector name, the GUI will name the vector smth_dep.`DISP`

Specifies how you want to display data. No default; you must specify an option.

**1**—

Unsmoothed data only

**2**—

Smoothed data only

**3**—

Both smoothed and unsmoothed data

You can control the attributes of the graph using standard ANSYS controls
(**/GRID**, **/GTHK**, **/COLOR**,
etc.). If working interactively, these controls appear in this dialog box
for convenience, as well as in their standard dialog boxes. You must always
