Matlab錯誤：尺寸不匹配 - 爲什麼？

Question

爲什麼我的代碼不工作？我想存儲array_one和array_two at one varibale - >output_array！我想讀取像output_array（1）和output_array（1）這樣的值，但它不起作用。我收到以下錯誤信息：

錯誤消息：

Subscripted assignment dimension mismatch.

Error in jaenner19 (line 37) output_array(1) = str2double(strsplit(diagramoptions.Value{strcmp(diagramoptions.Key, 'wsectionstart')}));

我的代碼：

wholecontent = fileread('test1.txt') 
sections = regexp(wholecontent, '\*+([^*]+)\*+([^*]+)', 'tokens') 

for section = sections 
    switch(strtrim(section{1}{1})) 
     case 'Diagram Options' 
      keyvalues = regexp(section{1}{2}, '([^\n\r=]+)=([^\n\r=]+)', 'tokens') 
      diagramoptions = cell2table(vertcat(keyvalues{:}), 'VariableNames', {'Key', 'Value'}) 
     case 'Diagram Limits' 
      header = strsplit(regexp(section{1}{2}, '[^\n\r]*', 'match', 'once')) 
      content = textscan(section{1}{2}, repmat('%f', 1, numel(header)), 'HeaderLines', 2) 
      diagramlimits = table(content{:}, 'VariableNames', header)  
     case 'Input Data' 
      inputdata = cell2mat(textscan(section{1}{2}, '%f%f%f', 'HeaderLines', 1))

有人可以幫我嗎？感謝你們。

Answer 1

你想要存儲的是一個數組，在output_array的第一行。 因此，嘗試：

output_array(1,:) = str2double(strsplit(diagramoptions.Value{strcmp(diagramoptions.Key, 'wsectionstart')})); 

下一行

PS當然output_array(2,:)和我建議你在代碼中的switch-case結構內部的線路添加semicolumns。
