Question

我有一个单元格数组，每行都有字符串。我想计算单元格数组每行中的字符数，包括空格。我如何在matlab中做到这一点？

感谢您的回答，我的代码中有点卡住了

fid = fopen('thenames.txt', 'w');
if fid ~= -1
    disp (' The file opened sucessfully')
else 
    disp (' The file did not open sucessfully')
end
string1 = input('Enter a name:','s');
countstr =1;
fprintf(fid, 'Name %d is %s\n', countstr, string1)
TF = strcmp ('stop', string1);
while TF == 0;
    countstr = countstr+1;
    string1 = input ('Enter a name:','s');
    TF = strcmp ('stop', string1);
    if TF ==0
fprintf(fid, 'Name %d is %s\n', countstr, string1)
    elseif TF == 1
            disp ('Ok. No more names')
    end

end
totalnames = countstr - 1;
fprintf(fid, 'There were %d total names given\n', totalnames)

fid = fopen('thenames.txt');
if fid ~= -1
disp (' The file opened sucessfully')
else 
disp (' The file did not open sucessfully')
end
cellarray2 = [];
cellarray2 = textscan (fid ,'%s %d %s %s');
newcellarray = {cellarray2{4}}
charsPerRow = sum(cellfun(@numel,newcellarray),2)

我最终试图以一个单元格数组结束，该单元格数组将名称作为字符串存储在第一列中，第二列将字符串中的字符数存储为整数。这将是我从cellarray2

开始的代码的最后一点

假设您有一个单元格数组C：

>> C = {'a','b2','c';'x','y','z';'aa','bb','cc'}
C = 
    'a'     'b2'    'c' 
    'x'     'y'     'z' 
    'aa'    'bb'    'cc'

然后使用cellfun和sum：

>> charsPerRow = sum(cellfun(@numel,C),2)
charsPerRow =
     4
     3
     6

假设您要将此标记为单元格：

>> C2 = [C num2cell(charsPerRow)]
C2 = 
    'a'     'b2'    'c'     [4]
    'x'     'y'     'z'     [3]
    'aa'    'bb'    'cc'    [6];

计算单元格数组中一行中的字符数，包括空格？
