y = legendre(n, x)

y = legendre(n, x, type)


Computes the associated Legendre functions of a given degree.



Name Description
n Specifies the degree of the Legendre function. n is a positive integer.
x Specifies the values at which to evaluate the Legendre function. x is a vector of double-precision, floating-point numbers. x must be between -1 and 1.
type Specifies the type of the Legendre function. type is a string that accepts the following values.

'norm' Computes the fully normalized associated Legendre function.
'sch' Computes the Schmidt, semi-normalized, Legendre function.
'unorm' (default) Computes the associated Legendre function.


Name Description
y Returns the Legendre function of degree n and order 0, 1, ... , n, evaluated for each element of x. If x is a vector of length m, y is an (n+1)-by-m matrix. The (i, j)-th element of y is the associated Legendre function of degree n and order i evaluated for the j-th element of x.
