Error: Assignment has more non-singleton rhs dimensions than non-singleton subscripts

Hi, i am trying to run a multi compartment model and I keep getting an error. I'm not sure what to do Error I keep getting:
Assignment has more non-singleton rhs dimensions than non-singleton subscripts
Here is my code:
clear all; close all; clc;
syms Cp(t) Cb(t) Ce(t) Cc(t) Cf(t)
t = [0 30];
Vb=5; %average blood volume (L)
k1 = exp(-0.1*t);
k23 = 33;
k32 = 20;
Ve = 14;
k34 = 33;
k43=20;
k5 = 50;
Vp = 1.37e-3;
Vc = 50e-6;
Vf = Vc;
ode1 = diff(Cp) == (-k1*Cp)/Vp;
ode2 = diff(Cb) == (k1*Cp-k23*Cb+k32*Ce)/Vb;
ode3 = diff(Ce) == (k23*Cb+k43*Cc-k32*Ce-k34*Ce)/Ve;
ode4 = diff(Cc) == (k32*Ce-k43*Cc-k5*Cc)/Vc;
ode5 = diff(Cf) == (k5*Cc)/Vf;
odes = [ode1; ode2; ode3; ode4; ode5]
S = dsolve(odes)
CpSol(t) = S.Cp
CbSol(t) = S.Cb
CeSol(t) = S.Ce
CcSol(t) = S.Cc
CfSol(t) = S.Cf
cond1 = Cp(0) == 100;
cond2 = Cb(0) == 0;
cond3 = Ce(0) == 0;
cond4 = Cc(0) == 0;
cond5 = Cf(0) == 0;
conds = [cond1; cond2; cond3; cond4; cond5];
[CpSol(t), CbSol(t), CeSol(t), CcSol(t), CfSol(t)] = dsolve(odes,conds)
fplot(CpSol)
hold on
fplot(CbSol)
