fopen with string vector

clear all
clc

cd('C:\Users\akess\Box Sync\PhD\PCCS\PCCS 190822\HRP with salt 190822\Textfiler')

S = dir('*.txt');
N = {S.name};

for j=1:length(N)

x = ones(2,length(N));
Name=N(j);
fid = fopen(Name); %THIS DOESNT WORK, DO YOU KNOW HOW TO FIX IT?
data = textscan(fid,'%s%s%s');

A=data{1, 2}{132, 1};%mean  count rate ch.1
B=data{1, 2}{134, 1};%mean  count rate ch.2
A1=str2num(A);
B1=str2num(B);
    x(1,j) = A1;
    x(2,j) = B1;
end

I have several files I want to read and only take out certain values. I would like the loop to open one file at a time but fopen does not seem to work with taking out one string from N. Can anyone help me?

try it :

clear all
clc
cd('C:\Users\akess\Box Sync\PhD\PCCS\PCCS 190822\HRP with salt 190822\Textfiler')
S = dir('*.txt');
N = {S.name};
for j=1:length(N)
x = ones(2,length(N));
Name=N{j};
fid = fopen(Name); %THIS DOESNT WORK, DO YOU KNOW HOW TO FIX IT?
data = textscan(fid,'%s%s%s');
A=data{1, 2}{132, 1};%mean  count rate ch.1
B=data{1, 2}{134, 1};%mean  count rate ch.2
A1=str2num(A);
B1=str2num(B);
    x(1,j) = A1;
    x(2,j) = B1;
    close(fid)
end

Thank you! works perfectly

Your first problem is that dir returns a structure. If you want the name of, the ith file it returns you should use

Name = S(j).name

You could also do it your way, making a cell array of file names, but I don't see any advantage to that. If you do it that way however you must use curly braces to retrieve the individual name for example

Name = N{j}

Thank you! Works!

Glad that it works now.
