Hi.
I'm trying to solve system of differential equations from
astrophysics.
It appears that I have made some misterious mistake in mathematica
code, but I have no idea where since all mathematica error
messages are absolutely non-informative.
Anybody can take a look ?
P.S.
I get the following errors:
Possible spelling
error: new symbol name "diffEqP" is similar to existing symbol
"diffEqM".
NDSolve::"ndnum":
"The right-hand side of the differential equation does not evaluate to
a \
number at r == 0.`.
