x=[1 zeros(1,N-1)];表示第一个位置是1，另N-1个0的行向量。y=[a,b]如果a,b为行向量，那么y就是把a，b行向量拼接成另一个新的行向量
x=[1 zeros(1,N-1)];表示第一个位置是1，另N-1个0的行向量。 y=[a,b] 如果a,b为行...
x=[1 zeros(1,n—1)] ②单位阶跃序列:这—序列可以利用MATLAB中的ones函数实现: x=ones(1,N) ③实指数序列: n=0:N一1: x=a.^n; ④复指数序列: n=0:N一1 x=exp((lu十J*w}*n); ⑤正弦波: t=0:0.0l*pi:2*pi; x=sin(2*pi*t); ...
zeros的用法如下 :参数可为变量 zeros(m,n)产生一个mxn的全零矩阵 zeros(m)产生一个mxm的全零方阵
产生一个1行N列的0矩阵。例如x0=zeros(1,5);则x0为[0 0 0 0 0]
zeros((N1+N2,N1+N2))) for i in range(N1): adj_block[i,N1+2*i] = 1 adj_block += adj_block.T mg = mx.MultilayerGraph(list_of_layers=[g1,g2],inter_adjacency_matrix=adj_block) Plot multiplex networks by layer # Create the figure fig = plt.figure() # Create 3D axes ax =...

1、如果，已知模型、参数和初值，只需要仿真一下，那么很简单，可采用如下程序：t=0:1:16;N=length(t);x=zeros(1,N);x(1)=1;%初始化 r=0.01;xm=10;for ii=1:N-1 x(ii+1)=x(ii)+r*(1-x(ii)/xm)*x(ii);end plot(t,x)2、如果只知模型结构和输入t输出x，不知道模型中...
y[n]+0.75y[n-1]+0.125y[n-2]=x[n]-x[n-1]。b. 单位冲激响应：(1)用filter函数 a1=[1,0.75,0.125];b1=[1,-1];n=0:20;x1=[1 zeros(1,20)];y1filter=filter(b1,a1,x1);stem(n,y1filter);title('y1filter');xlabel('x');ylabel('y');（2）用conv函数 a1=[1...
