Laguerre polynomials in MATLAB

Question

I tried using the .. command in MATLAB to generate Laguerre polynomials but I keep getting this error every time:

Answer 1

In R2014b+, there is a laguerreL function available directly from within Matlab. However, a version of this function was introduced to MuPAD in R2009a. You can call the MuPAD version from within Matlab

syms x;
feval(symengine,'laguerreL',2,x)

or

evalin(symengine,'laguerreL(2,x)')

Both return x^2/2 - 2*x + 1.

You can read more about interacting with MuPAD functionality from Matlab here. However, I'd recommend browsing and searching the archived documentation for your specific version or using your built-in HTML documentation (e.g., doc mupad or doc 'calling mupad').

Answer 2

Like you say, and the matlab help says this function only works inside mupad, maybe in later versions it works in matlab console.

If you want to use it, write mupad in Matlab Command window and then use it in the mupad, matlab will return you the result as I show in the picture
