MATLAB: Orthogonal polynomial function in matlab similar to the R function poly()

orthogonal

Is there any function in matlab that can produce orthogonal polynomial like the R function poly() for equal spaced point? I didn't quite find the corresponding function.

Best Answer

The Legendre and Jacobi polynomials are orthogonal and can be easily generated in using the Symbolic Math Toolbox.

I also found this book on the subject which includes a number of code examples.

MATLAB: Does poly() not evalp

sqrt( 1-x^2 ) is not a polynomial. evalp() is only for evaluating polynomials.

I am not familiar with the way you used "|" in your second expression. I looked through the Standard Library but I do not find any meaning defined for "|" . Could you give a reference on that?

MATLAB: Orthogonal vector to this

Orthogonal to what? The result is a 2x100 complex valued array.

Are you asking how to find a vector orthogonal to the rows of s?

That is trivial.

help null

It will give you a basis for the null space of the rows of s, in the form of a 100x98 matrix.

If you are asking something else, you need to explain what you are looking to find.
