我正在尝试从文件中读取数据，但我无法将格式从单元格更改为双格式，任何正文都可以帮助我。
我写的代码：
fid=fopen(filename);
tline = fgetl(fid);
while ischar(tline)
temp = strsplit(tline);% temp should be array holding double values.
end

您可以使用cell2mat()吗？
这会将您的单元格数组转换为与原始单元格数组中的值格式相同的矩阵。
从上面链接提供的示例：
c = {[1], [2, 3, 4];
[5; 9], [6, 7, 8; 10, 11, 12]};
m = cell2mat(c)
m =
1 2 3 4
5 6 7 8
9 10 11 12
答案 1 :(得分：1)
我认为你只是在寻找str2num。
假设您有一个包含两行数字的单元格，以字符串格式存储：
c={'0.0000000e+00 4.1800000e+01 4.4800000e+01';
'0.0000000e+00 4.1800000e+01 4.4800000e+01'}
现在你可以从第一行得到数字：
d=str2num(c{1})
这假设读书已经成功。否则请查看doc dlmread
