automate the transfer of text files iteraton wise

Dear All

I have 730 text files named as file_1.txt, file_2.txt, ...,file_730.txt which need to be transfered in MATLAB such that file_1.txt will be transfered during 1st iteration and so on. I don't know how to address such automation. Please help !

Below is the code for the 1st file to be read during 1st iteration:

fID = fopen('file_1.txt','r');
diffusion=textscan(fID,'%n %n %n','headerlines',7,'Delimiter','');
fclose(fID);

name = "file_1.txt";
filelist = string(zeros(730,1));
diffusion = cell(730,1);
for k = 1:730
    number = string(k); 
    filelist(k)=replaceBetween(name,"_",".",number);
    fID = fopen(filelist(k),'r');
    diffusion{k} = textscan(fID,'%n %n %n','headerlines',7,'Delimiter','');
    fclose(fID);
end

Thanks Stephan for your help....

You actually don't need replaceBetween here. The + operator for string arrays knows how to convert numbers into a string and concatenate that new string with the original string.

diffusion = cell(730, 1);
for whichfile = 1:730
    thename = "file_" + whichfile + ".txt";
    fID = fopen(thename, 'rt');
    diffusion{k} = textscan(fID,'%n %n %n','headerlines',7,'Delimiter','');
    fclose(fID);        
end

In fact, this is vectorized which can be useful if you need the list of all the file names.

whichfile = (1:10).';
thename = "file_" + whichfile + ".txt"

Implicit expansion works too.

ind = 1:5;
A = "x(" + ind.' + "," + ind + ")"
