如何在 MATLAB 中将空矩阵分配给元胞数组的元素？
我想操作一个元胞数组并使元胞数组的某些索引包含空矩阵[]。我似乎不知道该怎么做：
>> yy=num2cell(1:10)
yy =
[1] [2] [3] [4] [5] [6] [7] [8] [9] [10]
>> yy{1:2:end}=[]
??? The right hand side of this assignment has too few values to satisfy
the left hand side.
>> yy(1:2:end) = []
yy =
[2] [4] [6] [8] [10]
呸！似乎无法做我想做的事。我想在元胞数组中保留空元素，例如
[] [2] [] [4] [] [6] [] [8] [] [10]
有什么建议吗？我的索引向量可以是任意的，可以是索引形式，也可以是布尔形式，不一定是[1 3 5 7 9]。
I want to manipulate a cell array and make certain indices of the cell array contain the empty matrix []. I can't seem to figure out how to do this:
>> yy=num2cell(1:10)
yy =
[1] [2] [3] [4] [5] [6] [7] [8] [9] [10]
>> yy{1:2:end}=[]
??? The right hand side of this assignment has too few values to satisfy
the left hand side.
>> yy(1:2:end) = []
yy =
[2] [4] [6] [8] [10]
Bah! Can't seem to do what I want. I want to leave empty elements in the cell array, e.g.
[] [2] [] [4] [] [6] [] [8] [] [10]
Any suggestions? My index vector could be arbitrary, and either in index form or boolean form, not necessarily [1 3 5 7 9].

您可以做的是使用
()索引元胞数组（而不是内容），并将每个单元格更改为空单元格{[]}：另一种方法是使用DEAL 函数，但看起来有点难看：
What you can do is index the cell array (not the contents) using
()and change each cell to an empty cell{[]}:An alternative is to use the DEAL function, but it looks a bit uglier:
