Bifurcation Diagram will not graph

My code below will run but does not graph a bifurcation diagram it just results in an empty figure with axis, can anyone see what I have done wrong?

Thankyou

figure;

ax(1) = axes;

hold on

xlabel ('k');

ylabel ('C');

xlim([-2 2]);

ylim([0 40]);

x=1;

for k = [-0.5:0.1:1.6]

syms c

eqn = (1/10)*((c-23)*(25-c)*(c-29))-k ==0;

Solution = vpasolve(eqn, c);

x=x+1;

Solution

plot(ax(1), k, Solution)

end

Plot the points —

figure;
    ax(1) = axes;
    hold on
    xlabel ('k');
    ylabel ('C'); 
    xlim([-2 2]);
    ylim([0 40]);
x=1;
k = [-0.5:0.1:1.6];
Solution = cell(size(k));                                       % Preallocate
for k1 = 1:numel(k)
  syms c
  eqn = (1/10)*((c-23)*(25-c)*(c-29))-k(k1) ==0;
  Solution{:,k1} = double(vpasolve(eqn, c));
%   x=x+1
  plot(ax(1), k(k1), Solution{k1}, '.')
end
hold off
grid

Out = [k; cell2mat(Solution)]

Out = 4×22

Not what appears to me to be a bifurcation plot, however it is a plot!
