Is it possible to insert variables into a string like a legend or title? For example, I'm modeling a difference equation, and I'm using for-loops to test different parameters within the equation; is it possible to plot the results where the parameter value can be displayed in a legend or title with each for-loop iteration? Thanks!
x=zeros(1,100);
for p=1:3 %test different values for parameter lambda
lambda=p*20; %lambda changes arithmetically
for q=1:3 %test different values for parameter b
b=q;
for n=1:99
x(1)=1;
x(n+1)=lambda*x(n)/(1+x(n))^b;
end
figure
plot(1:100,x,'r')
end
end

title( sprintf('lambda = %f', lambda) );
