-------------------------------------------
Commenting out "_dagRuleSet.add( new RewriteIndexingVectorization() )" and/or
setting ALLOW_AUTO_VECTORIZATION to false doesnot resolve the issue :(
> Incorrect dimensions after left indexing operation

> Key: SYSTEMML-1081
> URL: https://issues.apache.org/jira/browse/SYSTEMML-1081
> Project: SystemML
> Issue Type: Bug
> Reporter: Niketan Pansare
>
> To reproduce this bug, please try following DML script:
> z = matrix (0, rows = 2, cols = 5);
> z[2, 2] = 2.5;
> z[2, 3] = 5.0;
> z[2, 4] = 10.0;
> n = ncol(z);
> print ("ncol (z) = " + ncol (z) + ", but n = " + n);
> This prints ncol (z) = 5, but n = 1.
> This occurs due to the line:
> https://github.com/apache/incubator-systemml/blob/master/src/main/java/org/apache/sysml/parser/StatementBlock.java#L694
