Overload List
| # | Signature | Description |
|---|---|---|
| 1 | procedure RayleighCDF(const X: TDenseMtxVec; b: Double; const Res: TDenseMtxVec); | Rayleigh distribution CDF (vectorized). |
| 2 | function RayleighCDF(x: Double; b: Double): Double; | Rayleigh cumulative distribution function (CDF). |
Overload 1: procedure RayleighCDF(const X: TDenseMtxVec; b: Double; const Res: TDenseMtxVec);
Rayleigh distribution CDF (vectorized).
| # | Name | Description |
|---|---|---|
| 1 | X | Distribution domain, positive real values or zeros. |
| 2 | b | Distribution parameter, positive real value. |
| 3 | Res | After calculation stores the CDF calculated from X and b. 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: function RayleighCDF(x: Double; b: Double): Double;
Rayleigh cumulative distribution function (CDF).
| # | Name | Description |
|---|---|---|
| 1 | x | Function domain, positive real value or zero. |
| 2 | b | Distribution scale parameter, positive real value. |
Returns: Double - the Rayleigh cumulative distribution function (CDF) for value x using the parameter b. x >= 0 and b > 0 are required, otherwise the result is NAN.
Remarks:
The Rayleigh cumulative distribution function is
CDF(x| b)=1-exp(-x^2/2b^2), x >= 0
Domain: x >= 0 and scale b > 0; the result rises monotonically from 0 (at x = 0) to 1. For b <= 0 or x < 0 the result is NAN.
