Question

我是Matlab的新手，所以我遇到了一个需要创建具有某些行和列名称的表的问题。

CameraCar = array2table(zeros(0,20), 'VariableNames',{"c1","c2","c3","c4","c5","c6","c7","c8","c9","c10","c11","c12","c13","c14","c15","c16","c17","c18","c19","c20"},'RowNames',{1:800});

我尝试在代码上使用上面一行，但在创建代码时遇到错误（如下所述）。

使用时出错   matlab.internal.tabular.private.rowNamesDim / validateAndAssignLabels   （第109行）RowNames属性必须是每个单元格的数组   包含一个非空字符向量的元素。

matlab.internal.tabular.private.tabularDimension / setLabels中的错误   （第173行）               obj = obj.validateAndAssignLabels（newLabels，indices，fullAssignment，fixDups，fixEmpties，fixIllegal）;

错误   matlab.internal.tabular.private.tabularDimension / createLike_impl（line   355）                   obj = obj.setLabels（dimLabels，[]）;

matlab.internal.tabular.private.tabularDimension / createLike中的错误   （第62行）                   obj = obj.createLike_impl（dimLength，dimLabels）;

表格/ initInternals中的错误（第206行）               t.rowDim = t.rowDim.createLike（nrows，rowLabels）;

table.init中的错误（第327行）               t = initInternals（t，vars，numRows，rowLabels，numVars，varnames）;

array2table错误（第64行）       t = table.init（vars，nrows，rownames，nvars，varnames）;

CarMatrix中的错误（第1行）CameraCar = array2table（零（0,20），   ＆＃39; VariableNames＆＃39; {＆＃34; C1＆＃34;＆＃34; C2＆＃34;＆＃34; C3＆＃34;＆＃34; C4＆＃34;＆＃34; C5＆＃34;＆＃34; C6＆＃34;＆＃34; C7＆＃34;＆＃34; C8＆＃34;＆＃34; C9＆＃34;＆＃34; C10＆＃34 ;, ＆＃34; C11＆＃34;＆＃34; C12＆＃34;＆＃34; C13＆＃34;＆＃34; C14＆＃34;＆＃34; C15＆＃34;＆＃34; C16＆＃34;＆＃34; C17＆＃34;＆＃34; C18＆＃34;＆＃34; C19＆＃34;＆＃34; C20＆＃34;}，＆＃39; RowNames＆＃39 ;, {1：800}）;

Answer 1

试试这个：

% Get your row numbers (optional as the table already gives these numbers
% as default)
rowNumbers = 1:1:800;
% Convert to cellarray
myCellArray = num2cell(rowNumbers);
% Convert numbers to strings
myCellArray = cellfun(@num2str, myCellArray, 'UniformOutput', false);
% Set up table
CameraCar = array2table(zeros(800,20), 'VariableNames',{'c1','c2','c3','c4','c5','c6','c7',...
    'c8','c9','c10','c11','c12','c13','c14','c15','c16','c17','c18','c19','c20'},'RowNames',myCellArray);

在Matlab中创建包含行和列名称的空表
