Overload 1: function ErfcInv: TMtxVec;
Calculates the inverse complementary error function for all calling object elements in-place.
Result: stored in self (calling object), returns self for chaining
Returns: x such that Erfc(x) equals the element value, for elements in 0..2.
Takes the complementary probability, which keeps both tails exact: y/2 is a power-of-two scaling and 1-y/2 is exact by Sterbenz. Prefer this over ErfInv(1-y), which caps the small-y tail at an absolute 5.55E-17.
Indexed: function ErfcInv(Index: Integer; Len: Integer): TMtxVec;
Calculates the inverse complementary error function for calling object elements [Index]..[Index+Len-1] in-place.
| # | Name | Type | Description |
|---|---|---|---|
| 1 | Index | Integer | start index |
| 2 | Len | Integer | element count |
Result: stored in self (calling object), returns self for chaining
An exception is raised if array borders are overrun or underrun.
Overload 2: function ErfcInv(const Src: TMtxVec): TMtxVec;
Calculates the inverse complementary error function for all Src object values.
| # | Name | Type | Description |
|---|---|---|---|
| 1 | Src | TMtxVec | source TVec or TMtx |
Result: stored in self (calling object), returns self for chaining
Stores the result in calling object. Size and TMtxVec.Complex properties of calling object are adjusted automatically.
Indexed: function ErfcInv(const Src: TMtxVec; SrcIndex: Integer; Index: Integer; Len: Integer): TMtxVec;
Calculates the inverse complementary error function for Src object elements [SrcIndex]..[SrcIndex+Len-1].
| # | Name | Type | Description |
|---|---|---|---|
| 1 | Src | TMtxVec | source TVec or TMtx |
| 2 | SrcIndex | Integer | source start index |
| 3 | Index | Integer | start index |
| 4 | Len | Integer | element count |
Result: stored in self (calling object), returns self for chaining
Stores the result in calling object elements [Index]..[Index+Len-1]. An exception is raised if array borders are overrun or underrun.
