将3个2维矩阵串成一个三维矩阵，cat(3,A,B,C)里面的3就是指沿着第3维方向连接 你就把3维矩阵想象成串在一根棍子上的3个“片”就行了，每一片分别是a、b、c3个 二维矩阵。clear all;clc;a=ones(3,3);b=magic(3);c=zeros(3,3);d=cat(3,a,b,c)d(:,:,1) = 1 1 1 ...

python3nppython3np.zero 1.定义数组,初始化数组我习惯性写成了这样:错误count = int[60]正确定义:count = [0]*60当然,还可以借用numpy库生成数组,可以得到多维数组:print(np.zeros(3)) print(np.zeros((3,3))) print(np.zeros((4,3,2)))结果:[0. 0. 0.][[0. 0. 0.] [0. 0. ...
If the end of the source C string (which is signaled by a null-character) is found before num characters have been copied, destination is padded with zeros until a total of num characters have been written to it. 拷贝num个字符从源字符串到目标空间。 如果源字符串的长度小于num,则拷贝完源...
abc0=zeros(1000,3);k=0;for c=3:1000 b=c-2;a=sqrt(c^2-b^2);if(mod(a,1)==0)k=k+1;abc0(k,:)=[a b c];end end abc=abc0(1:k,:);fprintf('所有勾股数 a b c=\n')disp(abc)最后得到所有勾股数：所有勾股数 a b c= 4 3 5 6 8 10 8 15 ...
