AdvancedMathSphericalHarmonic Method
Computes the value of a spherical harmonic function.

Namespace:  Meta.Numerics.Functions
Assembly:  Meta.Numerics (in Meta.Numerics.dll) Version: 3.1.0.0 (3.1.0.0)
Syntax
public static Complex SphericalHarmonic(
	int l,
	int m,
	double theta,
	double phi
)

Parameters

l
Type: SystemInt32
The order, which must be non-negative.
m
Type: SystemInt32
The sub-order, which must lie between -l and l inclusive.
theta
Type: SystemDouble
The azimuthal angle θ. This angle is usually expressed as between -π/2 and +π/2, with positive values representing the upper hemisphere and negative values representing the lower hemisphere.
phi
Type: SystemDouble
The cylindrical angle φ. This angle is usually expressed as between 0 and 2π, measured counter-clockwise (as seen from above) from the positive x-axis. It is also possible to use negative values to represent clockwise movement.

Return Value

Type: Complex
The value of Yl,m(θ,φ).
Exceptions
ExceptionCondition
ArgumentOutOfRangeExceptionl is negative, or m lies outside the range [-l, l].
