使用matlab中的其他向量元素创建矩阵(Create a matrix using elements of other vectors in matlab)

我有两个向量a，b

a=[1; 2; 3; 4] b=[1; 2; 3]

我想创建一个看起来像这样的矩阵

c=[1 1; 2 1; 3 1; 4 1; 1 2; 2 2; 3 2; 4 2; 1 3; 2 3; 3 3; 4 3]

I have two vectors a, b

a=[1; 2; 3; 4] b=[1; 2; 3]

And I want to create a matrix which will look like this

c=[1 1; 2 1; 3 1; 4 1; 1 2; 2 2; 3 2; 4 2; 1 3; 2 3; 3 3; 4 3]

最满意答案

这是另一种方式！

c = [repmat(a,numel(b),1),sort(repmat(b,numel(a),1))]

Here is yet another way!

c = [repmat(a,numel(b),1),sort(repmat(b,numel(a),1))]
