Example #1

        public static int GetDMatrixRowCount(IntPtr handle)
        {
            var error = 0ul;
            var res   = XgBoostWrapper.XGDMatrixNumRow(handle, ref error);

            return(res);
        }

Example #2

        public static IntPtr CreateDMatrixFromDenseMatrix(float[] data, int rowCount, int colCount, float missing = float.MinValue)
        {
            var res = XgBoostWrapper.XGDMatrixCreateFromMat(data, (ulong)rowCount, (ulong)colCount, missing);

            return(res);
        }
