创建一个字符串数组

Question

是否可以在for循环中在MATLAB中创建一个字符串数组？

例如,

for i=1:10
Names(i)='Sample Text';
end

我似乎无法这样做.

Answer 1

您需要使用单元格数组:

names = cell(10,1);
for i=1:10
    names{i} = ['Sample Text ' num2str(i)];
end

Answer 2

您可以创建一个通过循环执行此操作的字符数组:

>> for i=1:10
Names(i,:)='Sample Text';
end
>> Names

Names =

Sample Text
Sample Text
Sample Text
Sample Text
Sample Text
Sample Text
Sample Text
Sample Text
Sample Text
Sample Text

但是,使用REPMAT可以更好地实现:

>> Names = repmat('Sample Text', 10, 1)

Names =

Sample Text
Sample Text
Sample Text
Sample Text
Sample Text
Sample Text
Sample Text
Sample Text
Sample Text
Sample Text

Answer 3

另外一个选项:

names = repmat({'Sample Text'}, 10, 1)
