| #### Issue Description | |
| I'm a new user of nd4j, and I just installed nd4j 0.9.1 using SBT and tried running the following: | |
| ``` | |
| // Note, I only need to find eigs for symmetric matrices, | |
| // but this particular one is not symmetric. | |
| INDArray M = Nd4j.create(new float[]{-2,4,2, -2,1,2, 4,2,5}, new int[]{3,3}); | |
| IComplexNDArray eigs = Eigen.eigenvalues(M); | |
| System.out.println(eigs); | |
| ``` | |
| However, I'm getting a java.lang.UnsupportedOperationException at org.nd4j.linalg.factory.BaseBlasWrapper.geev(BaseBlasWrapper.java:462). | |
| Is this intended behavior? E.g. openblas does not support geev. Or a bug? | |
| Output: | |
| ``` | |
