Dear Mathematica users!
I can not pass a Complex number as an argument to the function below
- an error occures:
NDSolve::mconly:
For the method NDSolve`IDA, only machine real code is available.
Unable to
continue with complex values or beyond floating point exceptions.
Everethying is ok, when the number is declared as Real, but I
suppose it is so.
The function is of the form:
ndsolut[W_?NumberQ] := NDSolve[eqset /. {w -> W}, dVar, {z, z1, z2},
SolveDelayed -> True];
where 'eqset' is a set of differential equations, 'dVar' (complex in
general) is a function to be solved, z - independent variable, w/W -
parameters (complex in general).
The function is called in a following way:
W = 1.+1.*\[ImaginaryI]
ndsolut[W]
I will appreciate any suggestions
Thank you and best regards
