Good teacher

[@usamaiqbal3130]

The best video I have ever seen on youtube. Very Informative

[@RamKumar-ve6eo]

Crystal Clear explanation.

[@ZERINSHAIMAMEEM]

you are life savior :')

[@hanslegacy]

Love from Bangladesh University of Engineering and Technology

[@dr.sunilkumar103]

Best explanation sir.

[@asifraj321]

Very nice explanation.Can you make a video on Fourier curve fitting?

[@mathecian]

Great dear...

[@imtiazshah1775]

well explained

[@RamKumar-ve6eo]

I'm hoping the next video of curve fitting based on spline function.

[@ramakrishnanp.v6551]

Huge thanks sir 💗

[@malaikawaqar5202]

Well explained sir

[@fizzaatif286]

Thank you sir.

[@jaimecastillo1980]

Bro could put subtitles on the video? I wasn't able yo undestane really well what were you saying, also nice video bro, your example was very clear

[@ATTIQIQBAL]

Thanks for feedback. At the start i was making videos in urdu language. However, now my latest videos are in English. I will try to put subtitles on my previous videos.

[@syedhashimnaqvi3321]

Thank you sir❣️

[@funwithwaniarumaisaareeba7586]

sir why do we have two different values of y against single value of independent variable x=0.7?

[@ATTIQIQBAL]

Sorry that's a mistake.

[@engineervlogs913]

your code is giving different coefficient results from the built-in syntax of Matlab( p = fit(x,y,poly3) ). which to trust ?

[@ATTIQIQBAL]

For fit command you have to define polynomial by yourself first. I recommend to use polyfit(X,Y,n) where n is the degree of polynomial

[@mohdyusuf5195]

Do you have any video on curve fitting using Nonlinear least square method

[@umeiransari3507]

sir how do you select previously registered input in the command window, i couldn't do that i had to manually feed the same input again and again to test run it, please let me know

[@ATTIQIQBAL]

Use the up key ⬆️ of the keyboard

[@muradsaleem9746]

Sir Interpolation waly topic se kuch questions hain 😔😔

[@tsehayenegash8394]

Nice video but please pload english

[@pandohaman1]

Very helpful Sir 👍 1 question, how to find total error?

[@ATTIQIQBAL]

I don't understand what do you mean by total error. The one possibility is compute new y1 vector by putting values in the polynomial obtained by curve fitting and then subtract this y1 vector with the original vector y. Now you have error vector on which you could compute different norms. You can search about different norms to pick the required one.

[@rogelioisaiasramirezortega6422]

Good video ! One question... how I put more than 2 curve fitting in the same figure . I mean, matlab show you , much plots with their fitting in the same figure Please answer me fast you can ): Thank you

[@ATTIQIQBAL]

Just use the hold on command and run the code again for different fitting without closing the previous graph

[@siddharthssahu2319]

with the command "polyfit" the code will be very very simpler no ??? we dont have to write this much in the code ... am i right ??

[@ATTIQIQBAL]

Polyfit is MATLAB built-in command to apply curve fitting. This code is made for understanding the curve fitting and making it's code at basic level.

[@engineervlogs913]

polynomial with multiple variable, how to code ?

[@saicandidates3969]

Really nice sir... ❤❤ Can we plot graph by using another simple commands not linspace or polyval.....

[@ATTIQIQBAL]

Polyval is necessary in order to evaluate polynomial at some value while instead of linspace you can simply define x vector like x = X(1) : 100 : X(n)

[@vrushabhrode7937]

sir if there is large no of data then this code is ok or what?

[@ATTIQIQBAL]

Yes, there is no restriction of data but may be if the data is so much scattered then linear or parabolic fit are not enough to best fit the given data.

[@darshanjohncena8501]

Can you please comment the Entire code will be helpful..!!

[@cricketnewswithmukesh]

Sir how to plot take 3 data from commond window and plot 3 curve together?

[@ATTIQIQBAL]

If you want to plot 2D plot of three different curves then use hold on command after first curve plot and plot the 2nd curve and so on.

[@cricketnewswithmukesh]

@@ATTIQIQBAL thank you so much sir i got it

[@samraharif7510]

Well explained. How can I contact you?

[@ATTIQIQBAL]

[@honeykumar5700]

I wonder why you have not reached 1k subscribers (i think its YTs algorithm)

[@ATTIQIQBAL]

Haha maybe :D

[@honeykumar5700]

Btw love your Urdu Accent

[@ATTIQIQBAL]

Thank you brother.

[@honeykumar5700]

@@ATTIQIQBAL Bro can you please give me a code for Solving ODE with Picards method

[@ATTIQIQBAL]

Sorry I haven't tried it.
