function AddProduct(const Vec1: TMtxVec; const Vec2: TMtxVec): TMtxVec;
Add a product of two matrices.
Result: stored in self (calling object), returns self for chaining
Remarks:
Multiply Vec1 elements with coresponding Vec2 elements and add the result to the calling Matrix. The size of the calling Matrix is set implicitly.
Examples
var
a, x, y, expected: Matrix;
begin
a := [[1.0, 2.0], [3.0, 4.0]];
x := [[1.0, 2.0], [3.0, 4.0]];
y := [[5.0, 6.0], [7.0, 8.0]];
a.AddProduct(x, y);
expected := [[6.0, 14.0], [24.0, 36.0]];
if not a.IsEqual(expected, 1e-10, TCompare.cmpAbsolute) then
raise Exception.Create('Matrix.AddProduct: mismatch');

Indexed: function AddProduct(const Vec1: TMtxVec; const Vec2: TMtxVec; Vec1Index: Integer; Vec2Index: Integer; Index: Integer; Len: Integer): TMtxVec;
Multiply Vec1 elements [Vec1Index]..[Vec1Index+Len-1] with Vec2 elements [Vec2Index]..[Vec2Index+Len-1].
| # | Name | Type | Description |
|---|---|---|---|
| 1 | Vec1 | TMtxVec | |
| 2 | Vec2 | TMtxVec | |
| 3 | Vec1Index | Integer | |
| 4 | Vec2Index | Integer | |
| 5 | Index | Integer | start index |
| 6 | Len | Integer | element count |
Result: stored in self (calling object), returns self for chaining
Remarks:
Ad the results to the calling object elements [Index]..[Index+Len-1]. An exception is raised if Matrix.ConditionCheck is true and array borders are overrun.
