I have a set of files named, dipoles.0.5000.xvg , dipoles.5000.01.10000.xvg and so on. I need to read those files and save in a different data(k) matrix. In the below form I am getting an Invalid file identifier error.
clc
clear all
for i = [0 5000.01 10000.01 15000.01 20000.01 25000.01 30000.01 35000.01 40000.01 45000.01 50000.01 55000.01 60000.01 65000.01 70000.01 75000.01 80000.01 85000.01 90000.01 95000.01];
for j = 5000:5000:100000
for k = 1:1:20
Data(k) = import_xvg('dipoles.%i.%j.xvg');
end
end
end

fn = dir("dipoles*.*");
for i = 1:length(fn)
x{i} = readmatrix(fn(i).name, "NumHeaderLines", 27);
end
x
x = 1×2 cell array
{12×5 double} {18×5 double}
