Shoutout to everyone who has dropped a Super Thanks! I appreciate the support!

[@mvpang]

finally found someone who can concisely explain the function command of MATLAB. Thank you very much

[@SpartanProfessor]

You're welcome!

[@swissengineer8453]

We should stick to him, believe me he is one of a kind

[@arunachala_bird]

The support I needed in the most simplest way possible. THANK YOU

[@nawar7729]

Thank you so much for this comprehensive and sufficient explanation, but why did you stop publishing videos?!
I hope that you are well.

[@kuba2466]

GREAT VIDEO SPARTAN PROFESSOR, HELPED ME FINALLY UNDERSTAND FUNCTIONS.

[@Omar_Ebrahim]

Now, I can create my own functions!

[@hsahil_10]

Thank you for the clear explanation.

[@mokamoka9048]

I don't know how I would thank you. But I really appreciate your help ❤❤thank you so much 🙌🙌🙌

[@SpartanProfessor]

No problem! Glad it helped!

[@joeyroberts9443]

Love this content! thank you so much

[@muneebanaureen9540]

JazakAllah 💕

[@prowlawsm]

Thanks a lot
God bless you a lot

[@jjlom00]

thank you so much sir

[@BukhoMatikita]

thank you well explained

[@muhammadasimch7]

Brilliant work

[@robertburnett4845]

hey man great video i really appreciate your hard work

[@SpartanProfessor]

I appreciate that!

[@tame_stranger9713]

This video was helpful. Thank you!

[@SpartanProfessor]

Glad it was helpful!

[@swissengineer8453]

A great professor

[@brianngohofficial]

Thx for also providing examples this helps

[@SpartanProfessor]

No problem!

[@TomTalley]

Concise and complete...thanks. might even be called "Spartan" like.

[@SpartanProfessor]

Glad you liked it!

[@user-kx9by7jm8u]

Thank you Sir.....

[@naomibatista7909]

THANK YOUUUUU!!!!!

[@SpartanProfessor]

No problem!

[@antonioacostasantiago4790]

Yo ser have save me from hair pulling moment. Thank you.

[@mingqi3312]

Dear Sir, Thanks a lot! I have a question as below: if the input is a signal in a defined function that changes with the system time, such as the speed of a generator, how the output will be processed with different time periods, see splitting the simulation time into three parts. I tried to take the time as conditions, but not sure how to get that time out from programing.

[@SpartanProfessor]

I'm glad you liked the video! I'm happy to answer questions related to the contents of the video. But, I won't answer questions that may be related to a homework assignment or research project.

[@shrutiOP]

thank you :)

[@SpartanProfessor]

You're welcome!

[@asifraj321]

You have such an amazing technique to teach. hats off sir.
I request to make a video for the function which takes row data like the wall shear stress function which has cloud point [Xcoordinate Y coordinate Zcoordinate MagnitudeWSS XcomponentWSS YcomponentWSS ZcomponentWSS].

[@SpartanProfessor]

Thanks for the kind words. To clarify, would you like a video on a user-defined function that accepts a row vector as an input argument?

[@asifraj321]

Yes sir. actually, I have fluent CFD data and want to user-defined function in Matlab which takes that data as input for the post-process.

[@asifraj321]

Sir, i am eagerly waiting for your video. I hope you will make it very soon.

[@vegabondd]

Plz explain forr fuzzy set

[@vkARTChannel1]

❤

[@gramsta836]

why is every letter in every word being enunciated?

[@SpartanProfessor]

To generate a cleaner transcript for closed captions and better enable translation of the captions to other languages. Not all of the viewers are native english speakers.

[@vishvetpatel5159]

Thank you sir
