Overload List
| # | Signature | Description |
|---|---|---|
| 1 | void ExpPDF(TDenseMtxVec X, Double Mu, TDenseMtxVec Res) | Exponential PDF (vectorized). |
| 2 | Double ExpPDF(Double x, Double Mu) | Exponential probability density function (PDF). |
Overload 1: void ExpPDF(TDenseMtxVec X, Double Mu, TDenseMtxVec Res)
Exponential PDF (vectorized).
| # | Name | Description |
|---|---|---|
| 1 | X | Defines distribution domain, real vector or matrix with positive values or zero. |
| 2 | Mu | Defines distribution rate parameter. Mu must be a positive scalar. |
| 3 | Res | After calculation stores the PDF calculated from X and Mu. Length and Complex properties of Res are adjusted automatically to match Length and Complex properties of X. |
Result: stored in self (calling object)
Overload 2: Double ExpPDF(Double x, Double Mu)
Exponential probability density function (PDF).
| # | Name | Description |
|---|---|---|
| 1 | x | Function domain, real value >= 0. |
| 2 | Mu | Scale parameter (= the distribution mean), real value > 0. |
Returns: Double - the exponential probability density function (PDF) at x for scale (mean) Mu. Returns 0 when Mu <= 0 (NOT NAN).
Remarks:
Computes the exponential PDF
PDF(x|mu)= 1/muexp (-x/mu)
where mu (Mu) is the scale, equal to the mean (the reciprocal of the rate). Domain: x >= 0, mu > 0. Behaviour: for mu <= 0 the result is 0 (not NAN); note the implementation special-cases x=0, returning 1.0 there. A scalar form (this one) and a vectorized Dew.Math.TDenseMtxVec overload are provided.
