Struct contents reference from a non-struct array object
显示 更早的评论
syms Cx(t) Cp(t) Cs(t) mim Ks Yxs ms alpha beta;
mi = mim*Cs/(Ks+Cs);
y = dsolve(diff(Cx,t) == Cx*mi , diff(Cs,t) == -Cx*mi/Yxs - ms*Cx , diff(Cp,t) == alpha*diff(Cx,t) + beta*Cx , Cs(0)==34, Cx(0)==0.12);
solCx(t) = y.Cx
solCs(t) = y.Cs
solCp(t) = y.Cp
And i get "Struct contents reference from a non-struct array object". What should i change to fix this problem?

You check the class of y it is sym. You are trying to access it like a structure which is not correct.

dsolve is saying that it cannot find the solution. The result is the empty sym rather than a struct of results
