在 Matlab 中创建包含行名和列名的空表

Question

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

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的行，但在创建它时出现错误(如下所述)。

使用 时出错 matlab.internal.tabular.private.rowNamesDim/validateAndAssignLabels (109行)属性必须是单元格数组，每个 元素包含一个非空字符向量。

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

中的错误 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/初始化内部错误(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 中的错误(第 64 行) t = table.init(vars，nrows，rownames，nvars，varnames);

CarMatrix 中的错误(第 1 行) CameraCar = array2table(zeros(0,20)， '变量名称'，{"c1"，"c2"，"c3"，"c4"，"c5"，"c6"，"c7"，"c8"，"c9"，"c10"，"c11"，"c12"，"c13"，"c14"，"c15"，"c16"，"c17"，"c18"，"c19"，"c20"}，'RowNames'，{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);
