The following matrices of identical dimensions 13x13 fail when I use xpy in neanderthal :

#RealGEMatrix[float, mxn:13x13, layout:column, offset:0]
   ▥       ↓       ↓       ↓       ↓       ↓       ┓
   →    4.40E+4 4.69E+2    ⁙    4.99E+5 3.73E+4
   →    4.69E+2 3.40E+5    ⁙    2.24E+6 3.80E+4
   →       ⁙       ⁙       ⁙       ⁙       ⁙
   →    4.99E+5 2.24E+6    ⁙    6.86E+7 2.16E+6
   →    3.73E+4 3.80E+4    ⁙    2.16E+6 1.07E+5
   ┗                                               ┛

#RealDiagonalMatrix[float, type:gd mxn:13x13, offset:0]
   ▧                                               ─
   ↘       0.50    0.50    0.50    0.50    0.50    ⋯
   ┗                                               ┛

I'm guessing this is because one of them is a diagonal matrix and one is a dense matrix. How to convert the diagonal to dense ? Or, is there something else wrong ? Apologies for a fairly noob question.
