convert string to cell array
显示 更早的评论
I have a for loop that gives results that are constantly updating
x= 'A'
x= 'B'
x= 'C'
But I would like to convert that into x= {'A', 'B', 'C'}
Any Suggestions?

clear x
x{1} = 'A';
x{end+2} = 'B';
x{end+3} = 'C';
and so on

No. There is no way to give a command along the lines of "collect all of the values that were generated for X into a cell array. You need to put them into the cell array at the time you generate them (or at least before X changes). For example you might have
for K = 1 : 50
r = rand();
if r < 0.3
X = 'A';
elseif r < 0.38
X = 'B';
elseif r < 0.92
X = 'C';
else
X = 'D';
end
X_vals{K} = X;
end

numfiles = 0;
for k = 1 : numFolders
SubFolder = listOfFolderNames{k};
filePattern = fullfile(SubFolder, '*.xls*');
ExcelFiles = dir(filePattern);
if ~isempty(ExcelFiles)
for k2 = 1 : length(ExcelFiles)
numfiles = numfiles + 1;
AllExcel{numfiles} = fullfile(SubFolder, ExcelFiles(k2).name);
end
end
end
However, what I would do instead is look in the File Exchange for https://www.mathworks.com/matlabcentral/fileexchange/19550-recursive-directory-listing or https://www.mathworks.com/matlabcentral/fileexchange/32226-recursive-directory-listing-enhanced-rdir
