问题描述
我有一个向量,例如
vector = [1 2 3]我想将它在自身内复制 n 次,即如果 n = 3,它最终会变成:
I would like to duplicate it within itself n times, i.e. if n = 3, it would end up as:
vector = [1 2 3 1 2 3 1 2 3]对于任何 n 值,我怎样才能做到这一点?我知道我可以执行以下操作:
How can I achieve this for any value of n? I know I could do the following:
newvector = vector; for i = 1 : n-1 newvector = [newvector vector]; end不过这看起来有点麻烦.有没有更有效的方法?
This seems a little cumbersome though. Any more efficient methods?
推荐答案尝试
repmat([1 2 3],1,3)我会让你检查 repmat 的文档.
I'll leave you to check the documentation for repmat.
