从键盘上输入一个三行三列矩阵的各个元素的整型值后输出元素平均值

#include <iostream>
using namespace std;

template<class T>
double CreateMatrix(const int y,const int x){
double re=0.0;
T** m=new T*[y];
for(int i0=0;i0!=y;i0++)
m[i0]=new T[x];
for(int i=0;i!=y;i++){
for(int j=0;j!=x;j++){
cout<<"Please input the value at m["<<i+1<<"]["<<j+1<<"]:";
cin>>m[i][j];
cout<<endl;
}
}
cout<<"The Matrix you create:"<<endl;
for(int i1=0;i1!=y;i1++){
for(int j1=0;j1!=x;j1++){
cout<<m[i1][j1]<<'\t';
re+=m[i1][j1];
}
cout<<endl;
}
for(int k=0;k!=y;k++)
delete [] m[k];
delete [] m;
return re/(y*x)*1.0;
}

int main(void){
int x,y;
cout<<"Please input the Height and Width of the Matrix:"<<endl;
cin>
