I have a matlab figure with my real data and a fitted curve on that data. Can I extract the fitted values from that matlab figure?

Arpan - how was the fitted curve added to that plot? Which function or functions were used to create it?

If it contains a single line, then you can do something like this
fig = openfig('test.fig');
Line = findobj(fig, 'type', 'line');
x = Line.XData; % x-data
y = Line.XData; % y-data
If there are multiple lines, then the variable 'Line' will be an array. In that case, you can index into 'Line' to get data for a specific line. For example
x = Line(2).XData; % x-data
y = Line(2).XData; % y-data
this code access the 2nd line in array 'Line'

It means you have a single line in your figure file.
