Lecture 2 (FDTD) -- MATLAB introduction and graphics

[@KmazuzAbd]

Keep me updated Thank you ❤.

[@johnteran8889]

this is the best matlab plotting tutorial i have encountered.

[@empossible1577]

Thank you!

[@tymemada]

This is much better than my school class :D Thank you very much.

[@shannonliu298]

Wonderful Tutorial :D This is exactly a good quick-start for FDTD based on Matlab.

[@cryfier]

great video

[@empossible1577]

Thank you! This is quite an old video. Since I made this video I have created some revised and better content. You can see it under Topic 2 here: empossible.net/academics/emp4301_5301/

[@chehboubimededdine6746]

So many thanks man , i thinks that's the first video that really helped me. thatks again!!

[@crunchtime901]

Very informative. I got a lot from this lecture. Thanks!

[@empossible1577]

This and the next lecture have seen a lot of updates and improvements in the electronic notes, but I have yet rerecorded the lectures. Be sure the check the course website for the best and latest! emlab.utep.edu/ee5390fdtd.htm

[@crunchtime901]

Will do. Please continue to share.

[@empossible1577]

I will!

Great work sir. Thank you for the video, really helpful

[@hessamABD]

Many thanks, very helpful resources

[@empossible1577]

You are welcome!

[@sundarrajn1003]

extremely helpful..thanks a lot

[@lucagessi-creatives]

can the course be followed with octave?

[@empossible1577]

I am 99% sure the answer is yes. So far, everything I have tried in Octave has worked.

[@felixshen9369]

helpful! thanks

[@learnsfi2422]

Do you have any 3D plotting please help😣

[@empossible1577]

No, but 3D graphics in MATLAB is definitely on my to-do list to create. MATLAB is actually extremely powerful for 3D graphics. You can place cameras, light sources, etc.

sir what does the syntax [ h2=get(h,'parent'); ] do in matlab? I don't find any change in the curve after this.

[@empossible1577]

If you plot a line with a command like h = plot(x,y) h is a handle to all of the different properties of the line like color, style, width, etc. Now if you want to change properties such as font size on the axis labels, these are not properties of the line itself, but higher level properties. They are properties of the line's parent. In order to change those you must first get a handle to the parent of the line. You do this with h2 = get(h,'Parent') Thus, this line of code will not change anything in the plot. However, using the handle h2 you can change properties such as the tick marks along the axes, font size of the axes and their labels, etc.

[@deeptiiap6848]

Sir I am not able to access scat field and total field options in optical power section of analysis button, Please let me know whee is the problem?

[@empossible1577]

What analysis button? What optical power section? You must be talking about another piece of software.

[@deeptiiap6848]

No Sir . I am talking about FDTD itself, we have analysis option to which it has optical power section which is supposed to have total field and scat field, that is not showing in my fdtd, so i am asking what would e the possible fault.

[@empossible1577]

I think you are talking about some other piece of software. Unfortunately, I will not be able to answer your question.

[@kiranilyas079]

how can we add figures for making the movie ?

[@empossible1577]

I have some crude notes on making mp4 and gif animations in the latest version of the notes for this same lectures. You can find it at the bottom of Topic 2 at the following course website: empossible.net/academics/emp4301_5301/

[@dileeppavansurya7735]

sir where can I get the slides and the e-notes of your clases

[@empossible1577]

This section of notes has actually been moved to a different course entirely and has also been revised and improved. The official course website for FDTD is empossible.net/academics/emp5304/ The link to the course website that now has the MATLAB notes is empossible.net/academics/emp4301_5301/ The course websites have links to the notes, PDFs of the lecture notes and other resources. I recommend accessing the course materials through the website instead of KZbin.

Helpful！

[@lazik711]

Thank you for the video - but Matlab is expensive, and i don't have :( - i have python, c etc. - but good job

[@empossible1577]

Have you looked into using Octave? That is an open-source clone to MATLAB. I think it works very well.
