I have plotted the follwing two curves as in the image below (fig2).
For the curve in red I have used a matlab generated code to do some curve fitting for it and got the curve in the below image (fig1).
Now I would like to be able to add the fitted curve to the plot in fig2 for comparison reasons, is there a way to do that?
thank you in advance,

yeah you can use hold on before curve fitting
or
alternatively
figure(2); %the intended figure number on which you need plot
hold on
plot("your data")

your this line is creating a new figure
figure( 'Name', 'untitled fit 1' );
hence you are not able to get the plot on the same figure

i can no longer see your comment (why did you delete it)
you can also use this
%in the first section
fh = figure;
ax= axes('Parent',fh);
hold(ax,'on');
%then your two plots
plot(ax,'plot 1')
plot(ax,'plot 2')
%% then you can apply optimisation
%and now the fitted plot
plot(ax,'plot 3')
fh.Name = 'khan 1'; %you can name your figure
