MATRIX and Other Commands (MATRIX-END MATRIX command)

A matrix program is a single procedure within a session.

• No active dataset is needed to run a matrix program. If one exists, it is ignored during matrix processing unless you specifically reference it (with an asterisk) on the GET, SAVE, MGET, or MSAVE statements.
• The GET, SAVE, MGET, or MSAVE statements support both dataset references and physical file specifications. Take the following example:

  DATASET CLOSE ALL.
  NEW FILE.
  
  GET FILE 'Samples\English\Employee data.sav'.
  
  DATASET DECLARE corr.
  CORRELATIONS bdate to minority /MATRIX=out(corr).
  MATRIX.
  MGET  /file=corr/type=corr.
  PRINT CR.
  END MATRIX.

  The example uses corr as a reference to a virtual dataset. The correlation output can also be saved to a physical file.

• Variables defined in the active dataset are unavailable during matrix processing, except with the GET or MGET statements.
• Matrix variables are unavailable after the END MATRIX command unless you use SAVE or MSAVE to write them to the active dataset.
• You cannot run a matrix program from a syntax window if split-file processing is in effect. If you save the matrix program into a syntax file, however, you can use the INCLUDE command to run the program even if split-file processing is in effect.
