Hello everyone

I am trying to preprocess a large batch of text files in Matlab. To do this, I have to remove the first couple of lines from each of the files. Can anyone share me some code on how to do this? Thanks

@Zubier Abdullah: what have you tried so far?

在 MATLAB Online 中打开

this is the code i am using so far

files = dir('*.TXT') N = numel(files) count = 0;

for i = 1:N fid1 = files(i).name disp(fid1) a = fopen(fid1,'r') file_name = [sprintf('%1.0f',i) '.txt']; fopen(file_name,'w+');

    for K = 1:4
        inline = fgetl(a)
    end
    while ischar(inline)
        inline = fgetl(a)
        fprintf(file_name,'%s\n\r',inline)
    end
 fclose('all')
    end

so far it is only creating blank files and not replacing the content of the files as i wanted. I have a smaller program where it replaces the text from one file to another but i have already defined the names.
