----------------------------------------

             Summary: Codegen fails w/ compilation errors for ARIMA
                 Key: SYSTEMML-1638
                 URL: https://issues.apache.org/jira/browse/SYSTEMML-1638
             Project: SystemML
          Issue Type: Bug
            Reporter: Matthias Boehm


ARIMA fails with the following java compilation error for the shown generated operator:

{code}
public final class TMP14 extends SpoofRowwise { 
  public TMP14() {
    super(RowType.ROW_AGG, 0);
  }
  protected void genexecRowDense( double[] a, int ai, double[][] b, double[] scalars, double[]
c, int len, int rowIndex ) { 
    double TMP6 = LibSpoofPrimitives.vectSum(a, ai, len);
    double TMP7 = getValue(a, 5, rowIndex, scalars[0]-1);
    double TMP8 = TMP6 - TMP7;
    double TMP9 = TMP8 / 4;
    c[rowIndex] = TMP9;
  }
  protected void genexecRowSparse( double[] avals, int[] aix, int ai, double[][] b, double[]
scalars, double[] c, int len, int rowIndex ) { 
    double TMP10 = LibSpoofPrimitives.vectSum(avals, aix, ai, len);
    double TMP11 = getValue(avals, 5, rowIndex, scalars[0]-1);
    double TMP12 = TMP10 - TMP11;
    double TMP13 = TMP12 / 4;
    c[rowIndex] = TMP13;
  }
}
