求sum=2/1+3/2+4/3++++(n+1)/n,用C语言怎么写

matlab小段代码求解释function [R,mx,my,mse]=circle_detect(x,y)N=length(x);a1=2*(sum(x)^2-N*sum(x.*x));a2=2*(sum(x)*sum(y)-N*sum(x.*y));b1=a2;b2=2*(sum(y)^2-N*sum(y.*y));c1=sum(x.*x)*sum(x)-N*sum(x.^3)+sum(x)*sum(y.*y)-N*sum(x.*y.*y);c2=sum(x.*x C#求 1!+2!+3!+……..+20!= sum matlab 求亮度 程序,看不懂,function B=Brightness(Y)[m,n,d]=size(Y);b=0;if d==1B=sum(Y(:))/(m*n);endif d==3B(1)=sum(sum(Y(:,:,1)))/(m*n);B(2)=sum(sum(Y(:,:,2)))/(m*n);B(3)=sum(sum(Y(:,:,3)))/(m*n);end ,号在SUM里面是什么意思=SUM(B5+1,F5+1,5)*SUM(C5+1,D5+1,3)*2/10000 matlab里边这个sum（X,1）,sum（X,Examples:If X = [0 1 23 4 5]then sum(X,1) is [3 5 7] and sum(X,2) is [ 312];sum(X,1）是不是第一列求和啊?那为什么不是3 而是 [3 5 7] 那sum(X, 求教一道vfp题,求数列2/1、3/2、5/3、8/5.的前20项之和a=1b=2sum=0term=b/afor i=1 to 20sum=sum+term t=bb=a+ba=tterm=b/aendforsum=,sum求高手逐步讲解. c语言 π/2=1+1/3*2/5+1/3*2/5*3/7+1/3*2/5*3/7*4/9+...求π精确到0.0001double n,t,sum,pi;sum=1.0；n=1.0t=1.0；do{t=t*（n/(2*n+1)）；sum=sum+t;}while(n/(2*n+1) fortran明天考试,有个难题,谁能帮下,（1）SUM=1.0 J=1 DO WHILE(J.LE.3) F=1 DO I=2,2*J+1 F=F*I ENDDO SUM=SUM+F J=J+1 ENDDO PRINT*,SUM END求sum vb 求 1×2×3×.×99×100=Private Sub Form_Click()Dim i As IntegerDim sum As Integersum = 1For i = 1 To 100 Step 1sum = sum * iNext iEnd Sub 这个有什么问题啊? 求0+1+2+3+…+n的值.#includeusing namespace std;void main(){int i,sum=0,n;coutn;for(i=0;;i++){sum=sum+i;if(i>n)break;}cout 编程计算sum=1+1/3 +1/5 +···+1/(2*n-1) 其中n是整数 设n=19 求sum的 javascript 计算 sum=sum+(1*2) 怎么写?求好使代码 帮我分析下这个题目#define ADD(x) x+xmain(){int m=1,n=2,k=3;int sum=ADD(m+n)*k;printf(“sum=%d”,sum);}上面程序的运行结果是（ B ）A）sum=9 B) sum=10 C) sum=12 D) sum=18请说明清楚! vb编程实现求sum=1/1!+1/2!+1/3!+ +1/n! (n 求sum=2/1+3/2+4/3++++(n+1)/n,用C语言怎么写 VB编程 Dim sum As Double,x As Double sum = 0 x = 0 For i = 1 To 5 x = n / i n=n+1 sum=sum+x nextprint结果为,sum 为什么结果是1/2+2/3+3/4+4/5而不是1+1/2+2/3+3/4+4/5 帮忙运行一下这段matlab代码,并把结果复制给我.身边没有电脑,又想知道结果.format longsum =exp(0)+exp(1);for i =0:3sum=sum+4*exp(0.125+0.25*i);endfor i = 1:3sum =sum+2*exp(0.25*i);endsum=sum/24 公式=SUM（1,2,3）的结果是?
