TVec.RandGauss Method

Overload List

#	Signature	Description
1	function RandGauss: TMtxVec;	The pseudo random sample generator with Gaussian distribution.
2	function RandGauss(AMean: Double; AStdDev: Double): TMtxVec;	Fills the calling object values with pseudo random samples following the Gaussian distribution.
3	function RandGauss(Seed: Cardinal; AMean: Double; AStdDev: Double): TMtxVec;	Fills the calling object values with pseudo random samples following the Gaussian distribution.

Overload 1: function RandGauss: TMtxVec;

The pseudo random sample generator with Gaussian distribution.

Result: stored in self (calling object), returns self for chaining

Remarks:

Fills the calling object values with pseudo random samples following the Gaussian distribution with parameters: Mean = 0, StdDev = 1 ("Standard disctribution"). The value for the seed is obtained from the CPU clock.

Examples

var a: Vector;
begin
    a.Size(500,False);
    a.RandGauss;
end;

Overload 2: function RandGauss(AMean: Double; AStdDev: Double): TMtxVec;

Fills the calling object values with pseudo random samples following the Gaussian distribution.

#	Name	Type	Description
1	AMean	Double	pre-computed mean
2	AStdDev	Double	output std deviation

Result: stored in self (calling object), returns self for chaining

Remarks:

The algorithm uses parameter AMean and AStdDev. The value for the seed is obtained from the CPU clock.

Overload 3: function RandGauss(Seed: Cardinal; AMean: Double; AStdDev: Double): TMtxVec;

Fills the calling object values with pseudo random samples following the Gaussian distribution.

#	Name	Type	Description
1	Seed	Cardinal
2	AMean	Double	pre-computed mean
3	AStdDev	Double	output std deviation

Result: stored in self (calling object), returns self for chaining

Remarks:

The algorithm uses parameters AMean, AStdDev and Seed.
