I use Matlab2018b on iOS. csvread does not work. file not found

i use this code

validdatatypes = {'.csv'};

strPath = dir('/Users/***/mess1600');

lPath = struct2cell(strPath)';

lPath = lPath(cell2mat(lPath(:,strcmp('isdir',fieldnames(strPath)))) == 0 & contains(lPath(:,1),validdatatypes),:);

lPath = cellfun(@(a,b) [b '\' a],lPath(:,1),lPath(:,2),'uniformoutput',0);

format long;

data = cell(numel(lPath),1);

for n = 1:numel(lPath)

data{n} = csvread(lPath{n},3,0);

end

error is:

Error using csvread (line 35)

File not found.

Error in export (line 10)

data{n} = csvread(lPath{n},3,0);

anybody got an idea? it worked on windows

[madhan ravi]

means the file does not exist in your working directory

[benn]

but the file does exist

Answer 1

[madhan ravi]

Processing sequence of files (use xlsread() or readtable() to read the file)

[benn]

still the same error. file not found. i mean everything else works. in lPath are all the directorys.

[madhan ravi]

lpath % paste the results here

[benn]

cant, contains personal info. but i can tell you that in lpath there are directorys all sorted nicely in a 6x1 cell. and i have 6 csv files to read. however csvread somehow cant open the files and get their info into data{}. as i told in the beginning. it works fine with windows. only problem i have is here on iOS. could it be a bug?

[madhan ravi]

use xlsread() or readtable() ??

[benn]

i also tried to just set up a simple excel file with some values in it. used my code. everything works, my code finds the .xlsx document when i change .csv to .xlsx in validdatatypes and csvread to xlsread. however xlsread does not work. it says: file not found. unable to open file with directory ('rigth directory')

Benn's answer moved here for consistency:

i tried something else. i guess i know what the mistake is, but cant handle it. the pathnames in lPath are missing this: '..' around them, thats why csvread cant open them. how to i add those somehow?
