可以,先将每个式子左边中的ai按照从小到大排序,比如a1+a3-2*a2=5写成a1-2*a2+a3=5,每个式子都如此处理,以ai作为未知数来求A*a=b,其中A为n-1行n+1列的矩阵,b为n-1
#includeintmain(){inti=0;floatsum=0;intn;intx[n],y[n];printf("请输出计算的项数:");scanf("%d",&n);x[0]=2;x[1]
关键是要知道通项公式,然后用编程求很简单的...从逻辑上来说应该是:f(n)=f(n-1)*3+1,空掉的的二项分别是:36429524'至于程序,给个VB的,是非常简单的,这个例子把前20项全输出来
intfib(n){if(n
x=ones(100,6)*0.3;p=[0.30.310.3110.31340.3340.36];fori=2:100x(i,:)=p.*x(i-1,:).*(1-x(i-1,:));endplot
我给你代码:#include <stdio.h>#include <stdlib.h>#define N 47int fibo
#includeintFib(intm){if(m==1||m==2)return1;returnFib(m-1)+Fib(m-2);}voidmain(){intn,i;printf("请输入n的值
#include <stdio.h>int main(){int sum=0;int a=0;int b=0;int i
publicclassFibonacci1{publicstaticlongfib(intn){longf1=1,f2=1;longm=0;if(n
//把n变为2进制数//由低往高数位置,最低位为第0位//若第i位为1,就将k^i累加到ans//例如n是6,二进制数为:110,所以结果为k^1+k^2vark,n,ans:longint;i,t:
#include#defineN10inta[N];intb[N];intmain(){inti;for(i=0;i再问:能不能加点注释啊...再答:#include#defineN10inta[
下面的程序可以修改宏定义N的值来确定输出的数的个数#include#defineN30voidmain(){unsignedlonginta[N];inti,j;a[0]=1;a[1]=1;for(i
