Matthias Boehm resolved SYSTEMML-680.
-------------------------------------
Resolution: Fixed
Fix Version/s: SystemML 0.10
we now added explicit error handling for qr, lu, and eigen to point to the
correct usage via multi-return assignment.
> eigen() fails with "Unsupported function EIGEN" but diag() works

> Original Estimate: 0.5h
> Remaining Estimate: 0.5h

> Could be some simple error, since I'm new to SystemML
> I'm running a tiny DML script:
> X = read($Xin)
> ee = eigen(X)
> via some things to set up the matrix in scala, ending with
> val sysMlMatrix = RDDConverterUtils.dataFrameToBinaryBlock(sc, df, mc, false)
> val ml = new MLContext(sc)
> ml.reset()
> ml.registerInput("X", sysMlMatrix, numRows, numCols)
> ml.registerOutput("e")
> val nargs = Map("Xin" -> " ", "Eout" -> " ")
> val outputs = ml.execute("dum.dml", nargs)
> I could certainly be doing something wrong, but it does run if I replace
> eigen() with diag() and both are listed similarly in the guide
> http://apache.github.io/incubator-systemml/spark-mlcontext-programming-guide.html
> Is eigen() supported currently and does it require some installation of some
> library? I didn't see anything about that in the docs.
> Thanks, this looks super useful!
> This might just be a documentation bug, not a code bug, but I'm not sure how
> else to contact people about it and get it resolved. Are there forums?
