如果我有一个矩阵:A = [1, 5, 10]，是否在一行上设置a1 = A(1), b1 = B(1)等?我想做类似的事情:

If I have a matrix: A = [1, 5, 10], do I set a1 = A(1), b1 = B(1), etc. on one line? I want to do something like:

[a1 a2 a3] = Blah(A)

推荐答案

除了您可以在我链接的所有问题中找到的答案以外，还有另一种受此@gnovice帖子:

Aside from the answers you can find in all the questions I linked to, here's yet another one-liner inspired by this @gnovice post using SUBSREF:

>> A = [1 5 10];
>> [x y z] = subsref(num2cell(A), struct('type','{}','subs',{{':'}}))
x =
     1
y =
     5
z =
    10

基本上等同于:[x y z] = num2cell(A){:}(但是那是无效的语法)

Basically its equivalent to: [x y z] = num2cell(A){:} (but thats non-valid syntax)
