Re: Polynomial interpolation

Please see the first example. You need to feed polyfit two vectors, x and y of the same size. 

so define x and y separately in your case it looks like:

 x = [1, 2, 3, 4, ....]

y = [ 73, 99, 90, 24...]

and finally n is the number of points you want to fit the array to. n can equal up to # of point - 1.

Dear Sir/ Madam

 

I am new to Octave, and I was not able to work with the polyfit function.

I have the matrix listed below and I want to find  the polynomial coefficients that fit to the points x,y:

 

 

What should I do?

 

Thanks in advance,
