dotnetCHARTING Namespace > ForecastEngine.Options Class : AddExponentialSum Method


expCoeff
An array where the k-th term is the coefficient of the whole k-th exponential term within the sum.
coefficient
An array where the k-th term is the coefficient of the variable within the k-th exponential term within the sum (i.e. coefficient as shown above).
constant
An array where the k-th term is the constant shift of the exponential function of the k-th term within the sum (i.e. the constant term as shown above).
exponent
An array where the k-th term is the exponent of the exponential term within the k-th element of the sum (i.e. n as shown above).
Adds a sum of exponential functions to be used as basis elements.

C#  
public static void AddExponentialSum( 
   double[] expCoeff,
   double[] coefficient,
   double[] constant,
   double[] exponent
)

Parameters

expCoeff
An array where the k-th term is the coefficient of the whole k-th exponential term within the sum.
coefficient
An array where the k-th term is the coefficient of the variable within the k-th exponential term within the sum (i.e. coefficient as shown above).
constant
An array where the k-th term is the constant shift of the exponential function of the k-th term within the sum (i.e. the constant term as shown above).
exponent
An array where the k-th term is the exponent of the exponential term within the k-th element of the sum (i.e. n as shown above).

Remarks

Where each of the elements of the sum given will take the following form:

expCoeff * expn (coefficient * x + constant))
