在MATLAB中保存多个txt文件时，如何保存带有连续数字的文件名？

我有大约2000条数据，大小为7611 * 1。我想将每个数据另存为txt文件。我想以1.txt，2.txt，3.txt ...格式保存txt文件名，该怎么办？

另外，在保存数据时，我想将其保留为7611 * 1格式，该怎么办？在这一部分中，我将附加我编写的无法正常工作的代码。 请帮忙。谢谢。

    st = data which size is 7611*1

    for i = 1:2000

    data = fopen('%d.txt','w',i);   % The next code doesn't work. I wrote this code 
                                    % to tell you what form I want. 

    fprintf(data,'%d \n',st);       % I want to save as a column vector, but when I 
                                    % run it with the code next to it, the broken 
                                    % txt file is saved... I cant find reason..

I recommend using the sprintf command inside your for loop to create the file name, i.e.,

 for i = 1:2000
    fName = sprintf('%0.0f.txt',i)  # create file name
    data = fopen(fName,'w', ... );  # include additional specifications as needed
    fprintf( ... ) #  include specifications as needed
 end
