Output of previous command into input

25 views (last 30 days)
I wrote a code and I have found these values when I run. Now, how can I convert this outputs as inputs in the next code. I tried in this code but it doesn't work. I want to define these Ca1 Ca2 Ca3 Ca4 Cb1 Cb2 Cb3 Cb4 outputs as my x0 inputs in this function. Ca1 Ca2 Ca3 Ca4 Cb1 Cb2 Cb3 Cb4 values are given below.
x0=[Ca1 Ca2 Ca3 Ca4 Cb1 Cb2 Cb3 Cb4];
x=fsolve(@functiondescription,x0)
Ca2 =
1421/3468
Ca3 =
217/2312
Ca4 =
91/1156
Cb1 =
1/8
Cb2 =
2047/3468
Cb3 =
2095/2312
Cb4 =
1065/1156

If those variables are in the workspace, it should run without any problems.
Ca1 = ...;
Ca2 = ...;
Ca3 = ...;
Ca4 = ...;
Cb1 = ...;
Cb2 = ...;
Cb3 = ...;
Cb4 = ...;
x0 = [Ca1 Ca2 Ca3 Ca4 Cb1 Cb2 Cb3 Cb4];
x = fsolve(@functiondescription, x0)

These output are result of this:
syms Ca1 Ca2 Ca3 Ca4 Cb1 Cb1 Cb2 Cb3 Cb4
[Ca1, Ca2, Ca3, Ca4, Cb1, Cb2, Cb3, Cb4]=solve(Eqns_1st_Order)
It gives this error:
FSOLVE requires the following inputs to be of data type double: 'X0'.

Ca1 = double(Ca1); % same for others
