Python使用scipy模块实现一维卷积运算示例

import numpy as np
import scipy.signal
x = np.array([1,2,3])
h = np.array([4,5,6])
print(scipy.signal.convolve(x, h))#一维卷积运算

#include<iostream>
#include<cstdio>
#include<cstring>
#include<cmath>
#include<vector>
#include<queue>
#include<map>
#include<algorithm>
usingnamespace std;
#define INF 0xfffffff
#define maxn 100010
int main()
{
int m=5,n=5;
int a[5]={0,1,0,2,1},b[5]={0,1,0,2,1};
int i,j;
int k=m+n-1;//卷积后数组长度
int c[k];
memset(c,0,sizeof(c));//注意一定要清零
/**卷积计算**/
for(i=0; i<k; i++)
{
for(j=max(0,i+1-n); j<=min(i,m-1); j++)
c[i]+=a[j]*b[i-j];
cout<<c[i]<<" ";
}
/****/
cout<<endl;
}
