Question

我遇到了问题，我必须在Matlab中访问单元格的内容。但它不是一个普通的细胞。细胞中可能有一个细胞。我不知道第一个细胞有多少个水平。

所有单元格都具有维度（1，x）

所以可能 mycell{cell1{cell11{char1, char2}}, char3, cell2{char4, char5, char6}}

我必须得到char变量，我必须知道它们在哪里。

当我这样做时，会返回这种类型的单元格

get_param(path_to_busselector, 'Inputsignals')

path_to_busselector是Simulink中总线选择器的路径。

我可以硬编码，但是我只能处理固定数量的单元级别，这是一个问题。

我的想法是，我用while循环构造一些东西，可能还有eval命令。

这里我有一个示例模型Matlab example model和一个提供信号名称的skript。如果您运行命令signalnames = get_param(BlockPaths(Cellofbusselector))，那么就有一个像我一样的单元格。现在我想访问总线选择器中的信号，但我不想手动执行此操作。如果我想在skript中访问信号，我必须知道信号的完整名称。这是清楚的还是我无法告诉我想要什么。对不起，如果第二个陈述是真的，我会再试一次

所以在我得到信号的名称之后我可以做这样的事情 set_param(outporthandle_of_busselector, 'Outport', fullsignalname)

为此，我必须知道确切的信号名称。

感谢您的时间和想法

我找到了解决方案。它不是很好，但它确实有效。

抱歉，我本来希望发布图片，但我没有10个声誉。所以你必须从上面的链接下载它。

这是主要的skript，更进一步的是recursif函数。 skript也适用于所有其他带有公共汽车的Simulin车型。但是刚才它只是工作，如果只有一个总线选择器。但是，为多个总线系统和总线选择器编程并不多。

%%

            fullsignames{ii,1} = [fullbusname(2:end) '.' signalname{ii,kk}]

以下是recursiv函数的代码

function [signalname, buslevel, numofsig, busname] = f_get_complete_signalnames(buscell, buslevel, numofsig, signalname, busname)
%% Description
% This function returns the complete signal names which are stored in a
% bus. The name looks something like bus1.bus2.signal1. 


if nargin < 2;    buslevel = 1; end
if nargin < 3;    numofsig = 0; end
if nargin < 4;    signalname = {}; end
if nargin < 5;    busname = {}; end


buscellsize = size(buscell);

buscellsize(1);               % busvert is the vertical dimension of buscell
for kk = 1:buscellsize(1)
    if ischar(buscell{kk,1}) && buscellsize(2) == 1
        numofsig = numofsig + 1;
        signalname{numofsig, buslevel} = buscell{kk,1};

    elseif ischar(buscell{kk,1}) && buscellsize(2) == 2
        busname{buslevel-1} = buscell{kk,1};
        [signalname, buslevel, numofsig, busname] = f_get_complete_signalnames(buscell{kk,2}, buslevel, numofsig, signalname, busname);

    elseif iscell(buscell{kk,1}) && buscellsize(2) == 1
        buslevel = buslevel+1;
        [signalname, buslevel, numofsig, busname] = f_get_complete_signalnames(buscell{kk,1}, buslevel, numofsig, signalname, busname);
        buslevel = buslevel-1;
    end
end

end
