Simulation time is one thing and plotting the results is another one. Are you asking why plotting of 10000 points (already known) takes a lot of time? This may depend on the properties of graphics package you are using. For example using stars instead of dots, request to smooth the resulting figure (especially a surface rather than simple curve), reach color palette or demanding the high resolution graph. Maybe a different plotting package will perform better?

Thanks Marek Sir for your nice explanation.

Sir my main objective to combine number of curves in single plot in MATLAB. When i run the programe having monte carlo simulation , it takes long time near about 4-5 hrs. But i run programe for single or for two curves instead of 5-6 curves it takes less time to simulate.

Please tell me the method how can i combine number of different saved curves in MATLAB in single plot .

Less curves requested thus lower simulation time - isn't it quite obvious? I'm practically unfamiliar with MATLAB and therefore unable to give you sensible advice related to MATLAB's graphical capabilities. But ... if the results of your simulations (curves) can be stored as a plain ASCII file, in form of two columns, then gnuplot will plot it using (interactively) just a simple command:

> plot "filename" plot "filename" with lines plot "filename" with linespoints

in a matter of seconds.

In case of few curves (each in its own color on a screen) the command is:

> plot "file1" with lines, "file2" with lines, ...

The execution time is strictly proportional to the number of processed points, of course. Various enhancements of the final figure may be requested (say using different line type for each curve or color), some of them increase execution time.

The graphical package gnuplot is free and runs under Linux, Windows as well as on Mac computers.

Hope it helps.

Really Sir, your valuable suggestions help me.

I will try with gunplot...

Thanks and Regards

Dear Jagtar,

You can try matplotlib which is simple, powerful and you can use python libraries like numpy, scipy and pandas. It's efficient. Moreover, you can also called Gunplot from python.

Thank you Dear Maneval Sir for your guidance ..

Sure i will try to solve the problem with matplotlib.
