2	function Add(const X: TMtx; const Y: TMtxVec; const Z: TMtxVec): Matrix;	Result = X + Y + Z, where X is a Matrix
3	function Add(const X: TMtx; const Y: TMtxVec; const Z: Double): Matrix;	Result = X + Y + zScalar, where X is a Matrix
4	function Add(const X: TVec; const Y: TMtxVec; const Z: TCplx): Vector;	Result = X + Y + zScalar
5	function Add(const X: TVec; const Y: TMtxVec; const Z: TMtxVec): Vector;	Result = X + Y + Z
6	function Add(const X: TVec; const Y: TMtxVec; const Z: Double): Vector;	Result = X + Y + zScalar

Overload 1: function Add(const X: TMtx; const Y: TMtxVec; const Z: TCplx): Matrix;

Compute X + Y + zScalar, where X is a Matrix.

#	Name	Type
1	X	TMtx
2	Y	TMtxVec
3	Z	TCplx

Returns: Matrix

Overload 2: function Add(const X: TMtx; const Y: TMtxVec; const Z: TMtxVec): Matrix;

Compute X + Y + Z, where X is a Matrix.

#	Name	Type
1	X	TMtx
2	Y	TMtxVec
3	Z	TMtxVec

Returns: Matrix

Overload 3: function Add(const X: TMtx; const Y: TMtxVec; const Z: Double): Matrix;

Compute X + Y + zScalar, where X is a Matrix.

#	Name	Type
1	X	TMtx
2	Y	TMtxVec
3	Z	Double

Returns: Matrix

Overload 4: function Add(const X: TVec; const Y: TMtxVec; const Z: TCplx): Vector;

Compute X + Y + zScalar

#	Name	Type
1	X	TVec
2	Y	TMtxVec
3	Z	TCplx

Returns: Vector

Overload 5: function Add(const X: TVec; const Y: TMtxVec; const Z: TMtxVec): Vector;

Compute X + Y + Z

#	Name	Type
1	X	TVec
2	Y	TMtxVec
3	Z	TMtxVec

Returns: Vector

Remarks:

Computes the sum of three vector-based operands, X, Y, and Z, without creating temporary objects.

Examples

var
    X, Y, Z, A1, A2, A3: Vector;
begin
X := [1, 2, 3, 4];
Y := [2, 3, 4, 5];
Z := [3, 4, 5, 6];
A1 := X + Y + Z;
A2 := Add(X, Y, Z);
A3.Add(X, Y, Z);
if not A2.IsEqual(A1) then ERaise('Problem');
if not A3.IsEqual(A1) then ERaise('Problem');
end;

Overload 6: function Add(const X: TVec; const Y: TMtxVec; const Z: Double): Vector;

Compute X + Y + zScalar

#	Name	Type
1	X	TVec
2	Y	TMtxVec
3	Z	Double

Returns: Vector

Remarks:

Computes the sum of X and Y with an added scalar zScalar without temporary objects.

Examples

var
    zScalar: Double;
    X, Y, A1, A2, A3: Vector;
begin
zScalar := 3.0;
X := [1, 2, 3, 4];
Y := [2, 3, 4, 5];
A1 := X + Y + zScalar;
A2 := Add(X, Y, zScalar);
A3.Add(X, Y, zScalar);
if not A2.IsEqual(A1) then ERaise('Problem');
if not A3.IsEqual(A1) then ERaise('Problem');
end;
