Share we support linear algebra? Thank you for your hardworking, I'm so happy that we do not need to rember the damned "axis number" in normal situations. But sometime we should still use the functions of linear algebra like LUdepart or determinant.
Follow is the codes to explain some personal idea of new functions API.

code

```

Adata = np.random.randn(4,4,7) A = DataArray(Adata, dims=('x','y','z')) L, U = LUdepart(A, dims1='x', dims2='y',newdims='a') ```

result

```

L DataArray(x:4, z:7, a: 4) ... U DataArray(y:4, z:7, a: 4) ... L@U == A True ``` I think other essential linear algebra function in numpy can be wraped by this way so that we will can use their named axis version. Do you have any suggestions? Finally, thankyou again for your work.
