Question

我正在尝试使用数据创建一个多维数组。我有一个17x10x1024的空单元阵列：

C=cell(length(data(1,:)),10,1024);

 % length(data(1,:) = 17

然后我计算（在一个while循环（17次））矢量1024x1：

value = data(:,i) + randn(size(t))*noise_out;

现在我想将这些向量的值分配给数组，其方式如下：

'Name of Signal'                 []    []    []    []    []    []    []    []    []
    'in1'               [1024x1 double]    []    []    []    []    []    []    []    []
    'out1'              [1024x1 double]    []    []    []    []    []    []    []    []
    'in2'               [1024x1 double]    []    []    []    []    []    []    []    []
    'out2'              [1024x1 double]    []    []    []    []    []    []    []    []
    'in3'               [1024x1 double]    []    []    []    []    []    []    []    []
    'out3'              [1024x1 double]    []    []    []    []    []    []    []    []
    'in4'               [1024x1 double]    []    []    []    []    []    []    []    []
    'out4'              [1024x1 double]    []    []    []    []    []    []    []    []
    'in5'               [1024x1 double]    []    []    []    []    []    []    []    []
    'out5'              [1024x1 double]    []    []    []    []    []    []    []    []
    'in6'               [1024x1 double]    []    []    []    []    []    []    []    []
    'out6'              [1024x1 double]    []    []    []    []    []    []    []    []
    'in7'               [1024x1 double]    []    []    []    []    []    []    []    []
    'out7'              [1024x1 double]    []    []    []    []    []    []    []    []
    'in8'               [1024x1 double]    []    []    []    []    []    []    []    []
    'out8'              [1024x1 double]    []    []    []    []    []    []    []    []

我使用以下内容：

C(i,2,:) = {value};

% i is the number of loop from 2 to 17

，但问题是我确实得到一个字符串'[1024x1 double]'而不是矢量的实际值。

有什么想法吗？

Answer 1

你想要得到的东西对我来说似乎并不合理，因为你在单元格中有很多单个值，你宁愿使用向量。

我建议三个选择：

C=cell(length(data(1,:)),10);
C(i,2) = value;

它为您提供一个单元格矩阵，其中您的名字在一列中，而单元格则在其他列中包含您的信号向量

但实际上我建议不要在单元格数组中存储名称和信号。因此，如果您需要带有信号的3D矩阵，请将名称分开并创建：

C = zeros(length(data(1,:)),10,1024);
C(i,2,:) = value;

或考虑使用结构;

signal(1).name = 'in1'
signal(1).values = value
signal(2).name = 'out1'
signal(2).values = value2

这些都只是想法，我没有尝试过，因为你没有提供足够的信息。
