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

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 + ")"
