I am trying to solve two differential equations numericaly:
The output of the dsolve command is "Non-fatal error while reading data from kernel." (Finding the symbolic solution without the "numeric" and "range" parameters with dsolve gives the solution but I need to solve using the numeric parameter.)
I thought the problem was coming from the imaginary element in the first equation. But I can solve:
without problem. What can be the origin of this problem?
