得到一個單元格的層數

Question

那麼我得到了這個問題，我必須在Matlab中訪問單元格的內容。但它不是一個普通的細胞。細胞中可能有一個細胞。我不知道第一個單元有多少個層次。

所有細胞具有尺寸（1，X）

所以它可能是 mycell{cell1{cell11{char1, char2}}, char3, cell2{char4, char5, char6}}

我必須得到字符變量，我必須知道他們在哪裏。

這種類型的細胞被返回，當我爲此

get_param(path_to_busselector, 'Inputsignals') 

path_to_busselector是路徑到在Simulink總線選擇器。

我可以硬編碼它，但我只能處理固定數量的單元級別，這是一個問題。

我的想法是，我用一個while循環構造了一些東西，可能是用eval命令的東西。

這裏我有一個示例模型Matlab example model和給出信號名稱的skript。如果你運行命令signalnames = get_param(BlockPaths(Cellofbusselector))那麼有一個像我這樣的單元。現在我想獲得總線選擇器中的信號，但我不想親自去做。如果我想要在skript中訪問信號，我必須知道信號的完整名稱。這是清楚還是我只是無法告訴我想要什麼。對不起，如果第二個說法是正確的，我將再次嘗試

所以之後我得到的信號，我可以做這樣的事情 set_param(outporthandle_of_busselector, 'Outport', fullsignalname)

名稱，爲了這個，我要知道確切的信號名稱。

感謝您的時間和您的想法

Answer 1

嗯，我找到了一個解決方案。這不是很好，但它的工作原理。

所有的文件都可以downloded​​

對不起，我也喜歡張貼圖片，但我沒有10和聲譽。所以你必須從上面的鏈接中下載它。

這裏主要是skript，下面是一個recursif函數。 Skript也適用於所有其他Simulin車型的巴士。但如果只有一個總線選擇器，它現在才起作用。但編程幾個總線系統和總線選擇器並不多。

end   % for ii = 1:length(BlockPaths) 



buscell = get_param(BlockPaths{Cellofbusselector}, 'InputSignals'); 


[signalname, buslevel, numofsig, busname] = f_get_complete_signalnames(buscell) 


%% 

signalnamesize = size(signalname); 
for ii = 1:signalnamesize(1) 
    for kk = 1:signalnamesize(2) 
     if isempty(signalname{ii,kk}) 
     else 
      nrofbusnames = kk-1; 
      fullbusname = ''; 
      for i = 1:nrofbusnames

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

下面是從recursiv功能

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 

我希望我做這個右邊的代碼。這有助於某人。
