    I'll have to write to youtube to make your tutorials the first result when searching for matlab tutorials. It would've saved me a lot of trouble had it been that way. Never truly understood the usefulness of matlab till now. Thank you very much sir, this is such a pleasure!

    Best explanation on polyfit/polyval I've come across so far.

    love your explaination, even something might be basic, but still you explain it like the "hold on" command. Thanks

    If my instructor at university had given us your youtube page link instead of coming to lectures, I would love the whole course instead of thinking about life.

    Thank you sir!
    Is there a way to estimate a datapoint that is outside the provided data ? i think polyfit gives a great fit upto the given datapoints, but the curve changes direction after the last datapoint.

    Hi,
    How do you specify the start and end of a regression line based on min and max x-values? I use "length(x)"? How do I "integrate" it in after making a graph?
    Thank you,

    'Polynomial regression in MATLAB' ----> Sir, thank you very much. Few days ago started learning MATLAB and your videos are of great great help to me. Could you please explain how to calculate R^2 value? Could you also explain me how to calculate uncertainty associated with the new cubic fit values?

  • @tesfayesuszinare939

    wonderful piece of work. Dear Prof, How can I get Multilinear models - four regressor variables (x1; x2; x3 & x4) with Surface Fitting Tool in Matlab?
    To get Polynomial of second order : y = B + a1(x1)^2 + a2(x2)^2 +a3(x3)^2+a4(x4)^2 + a5(x1)(x2) + a6(x1)(x3) + a7(x1)(x4)+a7(x2)(x3)+a8(x2)(x4)+a9(x3)(x4) and how to use cftool
    Please give me some introduction to do this or any hint.
    Thanks a lot.

    Hi Robert,
    I have a problem and I would like some help if
    possible.
    I am busy studying the mutual influences of the price
    of one good on another. In order to do so, we came up with the following model
    Xi = αi - aPi + bPj (1)
    Xj = αj + bPi - cP j (2)
    I would like to use the Chebychev algorithm interpolation
    and Gaussian quadrature schemes to approximate the parameters αi, αj,
    a, b and c.
    I also know that this is linear system of equations

      Mrmalleableful I absolutely agree with you, because even if you take a text book written by a British, that is really difficult to read compared to one written by an american. Americans create academic and scholarly article to educate people while British write to show off their colors. But I cannot generalize this accusation, since there are lot of British scholars who are outstanding teachers.
