这个问题视具体函数而定!sum如何编写的,sum(x,y,可能跟xyz都没关系都可以呢!但通常是x,y,z的和,或者x,y的和保存到z.
sum(x,y,
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
sum(sum(Y~其中Y是矩阵.
有单字节无符号数X,Y,计算X+Y,运算结果放入SUM单元中.X,Y,SUM均为字节变量名.
x=1:2 和y=x.^2 sum(y) 这是什么意思(matlab)
matlab中的sum(X,
C语言:下面的功能是计算函数F(x,y,z)=(x+y)*(x+y)+(x+y)*(x-y)的值并输出.float f(float,float);main(){float x,y,z,sum;scanf(%f%f%f,&x&y&z);sum=_____________;printf(sum=%f'

sum+=x%2?x:
matlab用solve解方程syms x y c en fai;[x,y]=solve('log(y.*(1-x)/(x.*(1-y)))+en','y.*(1-c.*sum((k.*(y./x).^k)/sum(((y./x).*exp(en-2.*pi)).^k)))+x.*c.*sum((k.*(y./x).^k/sum(((y./x)*exp(en-2.*pi)).^k))-fai')Error using ==> solve' log(y.*(1-x)/(x.*(1-
fun(int x ,int y) {return(x+y);}main() { int a=1,b=2,c=3,sum;sum=fun((a++;b++,a+b),c++);printf(“%d
”,sum);}输出结果是多少?
Verilog Modelsim 程序问题——1位全加器源文件module adder(sum,co,cin,x,y);input x,y,cin;output sum,co;assign {co,sum}=x+y+cin;endmodule 测试文件`timescale 1ns/10psmodule adder_test;reg x,y,cin;wire sum,co;initial beginx=0;y=0;cin=0;#1
VB中赋值语句的有效性下列哪些赋值语句是有效的?sum=sum-sumx+2=x+2x+y=sumlast
Var x=3,y=2; Int I,sum=5; If (x>y) {for (i=1;i
matlab中sum(X(:,i).
看看这个lingo程序哪里出错了?model:sets:de/1..8/:x,y;fe/1..5/:f;link(fe,de):W;endsetsdata:x=5 7 5 4 6 5 5 3;y=25 36 32 15 31 28 22 12;L=20;enddatamin=@sum(de:x*w(1,j))+@sum(de:x*w(2,j))+@sum(de:x*w(3,j))+@sum(de:x*w(4,j))+@sum(de:x*w(5,j))+
请问 x=rand(1,3);y=sum(x);r=x/y 这个最后的r=x/y是表示什么意思?
请教高人.40.若以下变量均是整型,且num=sum=7;则执行表达式sum=num++, sum++,++num后sum的值为( )还有下面一道,为什么会保留这些位的小数位?41.若有定义:int a=7;folat x=2.5,y=4.7;则表达式x+a%3*(i
