Matrix Object Data Properties

The Matrix Properties dialog box controls the internal data type, data format, and data display properties of a matrix object. Thus, each object in a matrix sheet can, for instance, have a different internal data type (which determines memory allocation), or display numbers in a different format.

To open the Matrix Properties dialog box:

Activate the matrix window and select Matrix: Set Properties from the Origin menu.

Column Width

Specify the cell width in units of characters.

Display

Use the Display drop-down list to select between the decimal, engineering, and scientific display formats:

Digits

Select Default Decimal Digits to display all digits in a matrix cell as determined by the Number of Decimal Digits setting on the Numeric Format tab of the Options dialog box (Tools: Options).

Select Set Decimal Places to control the number of digits displayed after the decimal place (overrides the Number of Decimal Digits setting on the Numeric Format tab of the Options dialog box). Type the desired decimal place value (n) in the associated text box. This value determines the maximum number of digits displayed after the decimal point. If the field is blank, the default value is used (which is 5 for Double and 8 for internal data types).

Select Significant Digits to control the number of digits displayed. Type the desired significant digit value in the associated text box.

Data Type

Double is the only data type that supports missing values, and it is recommended for curve fitting and other math operations where high precision is needed.
