The first part were M1=M2=0, I can't introduce the initial values for x1(0=Vector[ 0.1:0.1:2] the code that I used is:
f=@(t,x)[x(2);x(1)-2*x(1)^3];
x1_cond=0.1:0.1:2;
x2_cond=0;
timespan=0:0.001:2;
[t,x]=ode45(f,timespan,[x1_cond;x2_cond]);
plot(t,x)
But there is a error for the initial conditions:
Error using vertcat
Dimensions of arrays being concatenated are not consistent.
Please help me I am new using Matlab

Where is blue part?
You should use for loop to calculate for different γ
gamma = 0.1:0.1:2;
for i = 1:length(gamma)
x1_cond=gamma(i)
% ...
end
