函数功能：本函数将完成对输入的 8*8 矩阵按照 zigzag 排列抽取数据

matrix 为输入矩阵

select==1 为正变换，select==2为反变换

zigdone 为输出矩阵-Function: This function will complete the input of 8* 8 matrix of data collected in accordance with the zigzag array matrix as input matrix select == 1 for the transformation, select == 2 for the inverse transform matrix for the output zigdone
