             Summary: Extend outer template support for matrix-scalar ops on sparse driver
                 Key: SYSTEMML-1886
                 URL: https://issues.apache.org/jira/browse/SYSTEMML-1886
             Project: SystemML
          Issue Type: Sub-task
            Reporter: Matthias Boehm


This task aims to support additional sparse-safe matrix-scalar operations on top of the sparse driver of an outer product codegen template. This includes, for instance, the {{X!=0}} in below example

{code}
((X!=0)*(U%*%t(V)+eps)) %*% V
{code}
