Hello!

I wanna ask you the next question.

I have system of four linear differential equations and solution of it (four functions f1,f2,f3,f4). When I try to verify my solution by odetest() I get a set of values: 0 and two bulky expressions with imaginary units.

So, I can't understand exactly my solution is right or not?

 

sysODE:={bla bla bla}{f1,f2,f3,f4}(x);
solsysODE:={f1(x)=........,f2(x)=......,f3(x)=......,f4(x)=.......};
misalign:=odetest(solsysODE,sysODE);
nops(%)
3
op(1,misalign) # zero
op(2,misalign) # not zero
op(3,misalign) # not zero

 

Thank you!
