property IsSubRange: Boolean;
Set to true after the SetSubIndex or SetSubRange call.
Returns: Boolean
Remarks:
This property is set to true after the Matrix.SetSubIndex or Matrix.SetSubRange call. If IsSubRange is true then the TVec method/function will be performed on subrange of values. Use Matrix.SetFullRange to set IsSubRange back to False and thus reset sub range to full Matrix length.
