Hi Richard,
If you copy one of the odd expressions in the matrix A
and paste it into a text editor or into this answer form you will see that there is an odd character sequence at the end \.10
-6249.804693603325` (-0.0012229040441303532` - 3.203739988383671`*^-11 \.10)
that is what is preventing the expression from being evaluated. It is the "funny character" that Daniel referred to in the definition of Gkp4j0
. It is rendered as a space in the notebook at the end of the definition, so it is not obvious. If you delete it, save the notebook, restart the kernel and evaluate, matrix A
no longer has those odd expressions.
