Description

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?
