FactorModel.AddCosineSum Method 

Adds a sum a Cosine functions to an elements of the function basis.

Parameters

cosCoeff

An array where the k-th term is the coefficient of the (k+1)-th term of the sum of Cosine terms (i.e. ak).

coefficient

constant

An array where the k-th term is the constant shift in the x-axis of the Cosine term of the (k+1)-th term of the sum of Cosine terms (i.e. ck).

exponent

An array where the k-th term is the exponent of the Cosine term of the (k+1)-th term of the sum of the Cosine terms (i.e. bk).An array where the k-th term is the exponent of the Cosine term within the (k+1)-th term of the sum of the Cosine terms (i.e. nk).

Remarks

Please note that the k-th term of the sum which makes up the basis function will take to form:

k-th Term = ak * (Cosnk (bk * x + ck)),

where the Cosine function is in terms of radians, and ak, nk, bk, ck are real numbers. Please, in order to construct the sum you just sum over k starting at 0.

Notes on the Radian measure

Radians are a means by which to describe the angle and are related to the more commonly used degrees as follows:

360 degrees = 2 * Pi * radians

therefore, 1 radian = 180 / Pi degrees = 57.295... degrees.
