Experimental
Computes the value of the n-th Legendre polynomial at a specified point. Currently only 64 bit floating point is supported.
This is an elemental function.
result = [[stdlib_specialfunctions(module):legendre(interface)]] (n, x)
n: Shall be a scalar of type real(real64).
x: Shall be a scalar or array (this function is elemental) of type real(real64).
The function result will be the value of the n-th Legendre polynomial, evaluated at x.
Experimental
Computes the value of the first derivative of the n-th Legendre polynomial at a specified point. Currently only 64 bit floating point is supported.
This is an elemental function.
result = [[stdlib_specialfunctions(module):dlegendre(interface)]] (n, x)
n: Shall be a scalar of type real(real64).
x: Shall be a scalar or array (this function is elemental) of type real(real64).
The function result will be the value of the first derivative of the n-th Legendre polynomial, evaluated at x.
