ENVI中求两幅影像的相关系数

1 # 求两个list中的共同元素 2 def commonElement(): 3 a=[1,2,3,5,6]; 4 b=[1,2,5]; 5 commonEle=[val for val in a if val in b]; 6 commonNum=len(commonEle); 7 return commonEle,commonNum; 运行结果: import randMatrix;为自己建立的模块 1 >>> import randMatrix; 2 >>>

对于两个数组 arr1=[1,3,4,5,8,9] arr2=[2,3,7,8,9] 求出交集与并集 test.java 1 import java.util.ArrayList; 2 import java.util.Collections; 3 4 5 public class test1 { 6 public static void main(String[] args) { 7 ArrayList<Integer> tmplist=new ArrayList<Integer>

QPointF MapEditor::getIntersectPos(QPointF posA, QPointF posB, QPointF posC, QPointF posD)//返回AB与CD交点,无交点返回(0,0) { QLineF line1(posA, posB); QLineF line2(posC, posD); QPointF interPos(0,0); QLineF::IntersectType type = line1.intersect(line2, &interPo

求二叉树中任意两个结点的距离 实现步骤: 计算跟到第一个结点的距离: 计算跟到第二个结点的距离: 计算lca: 计算跟到lca结点的距离: 结果为(1) + (2) - 2 * (4),因为重复计算了两次的从跟到lca结点的距离: 1 class Node(object): def __init__(self, value=0): self.value = value self.left = self.right = None def get_path_length(root, n, path)

#include<stdio.h> int *max(int *x,int *y) { int *q; if(*x>*y)  q=x; else  q=y; return q; } void main() { int a,b,*p; scanf("%d,%d",&a,&b); p=max(&a,&b); printf("%d,%d,max is %d\n",a,b,*p); } 编程题:返回指针值的函数,求两个数中较

#include<stdio.h> void main() { float min(float x,float y);  /*函数定义在调用的函数之后,要先声明*/ float a=3,b=4.1; printf("%.1f\n",min(a,b)); printf("%.1f\n",min(5,a*b)); printf("%.1f\n",min(b-1,min(a,b))); } float min(float x,float y

在C语言中如何求两个数的最大公约数呢?下面用三种方法进行求解. 方法一:穷举法. 先比较两个数的大小,然后找出较小数t,最后判断t为何值时两个数都能整除,此方法效率较低. 代码如下: #include<stdio.h> int main() {      int num1,num2,temp,i;      scanf("%d%d",&num1,&num2);      if(num1>num2)      {            temp=num1
