The Matrix Properties sheet lists all kind of important information on a selected matrix. In fact, all relevant information that is stored in the object definition file of the matrix is displayed. For more information, refer to Basic concepts : properties of objects.
The Matrix Properties sheet appears:
General tab: |
|
Object type and name: |
Principal Components Coefficients "object name", or Factor Analysis Coefficients "object name". When you click this flat button, the matrix will be (re)opened. |
Location: |
The path and directory where this object is stored. |
Object date and time: |
Date and time when this object was last changed. |
Object size: |
Total size of the object on disk in bytes (.MAT). |
Read only: |
Select this check box to make the object read only. Clear this check box to make the object changeable. |
Description: |
Description of the object; freely editable. The description of a matrix is visible on the status bar of the Main window when moving the mouse pointer over the object in a Catalog. |
Dependency tab (for dependent matrices): |
|
Object type and name: |
Principal Components Coefficients "object name", or Factor Analysis Coefficients "object name". When you click this flat button, the matrix will be (re)opened. |
Definition: |
The expression by which the object was created is listed, i.e. the object definition. |
Up-to-date or not: |
Lists whether this matrix is up-to-date or not. If not, the name of the object which was changed last is shown including that object's date and time. |
Depends on: |
In a tree view, the names of the objects are listed on which this matrix depends. |
Calculate: |
When the matrix has only been defined by its object definition:
|
Make Up-to-Date: |
When the matrix is not up-to-date anymore, i.e. when one or more objects on which this matrix depends have been changed, and when the matrix has been calculated already:
|
Release Disk Space: |
When the matrix has been calculated already:
The expression by which this dependent matrix was created remains stored in the object definition file (.MAT), so this matrix can always be recalculated. |
Break Dependency Link: |
Whether this matrix is Up-to-Date or not:
Do not break the dependency link if you wish to be able to update this matrix in a later stage on the basis of changed input objects. |
Additional Info tab (when the matrix has been calculated): |
|
Object type and name: |
Principal Components Coefficients "object name", or |
Additional info: |
The total variance of each input band in the map list is listed and the percentage variance of each band that accounts for the eigenvalues. |
