=(a.length

=(a.length length:+a.length 还有 a[i]+ if(a[i]==a.length-1)是什么意思 a.Length 和a［i].Length各是什么意思 output += input[input.Length - matlab中f=[x zeros(a,N-length(x))];其中x是变量,function XF=gfft(x,N,k)if length(x) matlab新人,想把矩阵中的符号变量替换为数值变量,程序运行结果不对,程序为：x=-1:0.5:1;y=x;syms t sf=[1 t s t+s];A=zeros(length(x).*length(y),4);for n=1:length(x)*length(y); for i=1:length(x); for j=1:length(y); A(n,:)=subs( for(i=a.length-1;i>=0;i--)怎么理解 #include using namespace std;class Box{public:Box(int a,int b,int c){height=a;width=b;length=c;}Box(const Box &b){height=b.height;width=b.width;length=b.height;}int volume(){return(height*width*length);}private:int height;int width;int length;};int m Index and length must refer to a location within the string. Parameter name: length.这是什么意思? matlab for i=1:length(y) for i=1:length(t)是什么意思 >> clear >> a=[1,-2,1.1];b=[1,2];c=1;d=4; >> na=length(a)-1;b=[zeros(1,d-1) b];nb=length(b)-1; >> a初学matlab,在编程时总是出现如下问题,>> clear>> a=[1,-2,1.1];b=[1,2];c=1;d=4;>> na=length(a)-1;b=[zeros(1,d-1) b];nb=length(b)-1;>> aa=con length函数的作用>> a=[+1 +1 +1 -1 -1 -1 -1 +1 -1 +1 -1 -1 +1 +1 -1]；>> p=length(a)p = 14 p的结果为什么是14而不是15呢 matlab中x=ones(1,n),以及q=zeros(1,n)中,n=length(a) in the diagram ABCDEF is a prism of length 36cm the cross-section ABC is a right-angled triangleAB=19cm and AC=14cm Calculate (a)the length BC (b)the total surface area of the prism (c)the volume of the prism (d)the length CE (e)the angle between the A sperm whale is________than a killer whale in its length (*L).length=0和L->length=0 作用一样?
