TVecByte.GetRow Method

Overload List

#	Signature	Description
1	function GetRow(const Mtx: TMtxInt; Row: Integer): TVecInt;	Copies a row from matrix.
2	function GetRow(const Mtx: TMtxInt; Row: Integer; Col: Integer; Len: Integer): TVecInt;	Copy the Row-th column elements [Col]..[Col+Len-1] to calling vector.
3	function GetRow(const Mtx: TMtxInt; Row: Integer; Col: Integer; Index: Integer; Len: Integer): TVecInt;	Copy the Row-th column elements [Col]..[Col+Len-1] to calling vector elements [Index]..[Index+Len-1].

Overload 1: function GetRow(const Mtx: TMtxInt; Row: Integer): TVecInt;

Copies a row from matrix.

#	Name	Type	Description
1	Mtx	TMtxInt	source TMtxInt
2	Row	Integer

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

Remarks:

Copies the Row-th row from Mtx matrix to calling vector. The TMtxVecBase.Length and TMtxVecInt.IntPrecision properties of calling vector are adjusted automatically. An exception is raised if condition checking is enabled and Row is greater than Mtx.Rows-1.

Examples

var a: TVecInt;
    b: TMtxInt;
begin
    CreateIt(a);
    CreateIt(b);
    try
        b.SetIt(2,2,[1,2,
            3,4]);
        a.GetRow(b,0); // a now contains [1,2]
    finally
        FreeIt(a);
        FreeIt(b);
    end;
end;

Overload 2: function GetRow(const Mtx: TMtxInt; Row: Integer; Col: Integer; Len: Integer): TVecInt;

Copy the Row-th column elements [Col]..[Col+Len-1] to calling vector.

#	Name	Type	Description
1	Mtx	TMtxInt	source TMtxInt
2	Row	Integer
3	Col	Integer
4	Len	Integer	element count

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

Remarks:

The TMtxVecBase.Length and TMtxVecInt.IntPrecision properties of calling vector are adjusted automatically. An exception is raised if condition checking is enabled and column array borders are overrun.

Overload 3: function GetRow(const Mtx: TMtxInt; Row: Integer; Col: Integer; Index: Integer; Len: Integer): TVecInt;

Copy the Row-th column elements [Col]..[Col+Len-1] to calling vector elements [Index]..[Index+Len-1].

#	Name	Type	Description
1	Mtx	TMtxInt	source TMtxInt
2	Row	Integer
3	Col	Integer
4	Index	Integer	start index
5	Len	Integer	element count

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

Remarks:

The TMtxVecInt.IntPrecision property of calling vector must be set explicitly. An exception is raised if condition checking is enabled and column array borders are overrun.
