prealloc()

如何在一个for循环上实现此代码或者只在一个循环中我如何使用嵌套循环来做到这一点

Answer 1

您可以将for循环组合成一个包含多个变量的循环。

function prealloc()
    situation=zeros(Int64,3^5,5);
    i=1;
    for north=0:2, south=0:2, east=0:2, west=0:2, current=0:2
        situation[i,:]=[north, south, east, west, current]
        i+=1
    end
    situation
end
