reading matrix data

[Maguin, Eugene]

Is it possible to use spss to read matrices written in, my made-up term, 'row concantenated' format?
Example: lower triangular
1
2 3
4 5 6

Row concatenated
1 2 3
4 5 6

I don't think so using either read matrix or matrix data. Anything else?

You could also read the data as a single column and reshape it using a few lines of code within MATRIX.

GET X / FILE * / VAR ALL.
COMPUTE COV=MAKE(3,3,0).
LOOP I=1 TO 3.
+  LOOP J=1 TO I.
+     COMPUTE COV(I,J)=X(I*(I-1)/2+J).
+     COMPUTE COV(J,I)=COV(I,J).

END LOOP.
PRINT COV.
END MATRIX.
