MATLAB: Filesep error Unexpected Matlab expression

filesep error unexpected

Good morning,

i'm creating a script which will work on Unix and Windows so i need to solve the problem of different directory mode / \; i read i have to use filesep but matlab gives me error

I wrote

delete('Risultatigiorno' filesep '*.txt');

Unexpected MATLAB expression. Why?

I have another question, if i write

pathout='Risultatigiorno' filesep;

is it right? Thank you

Use square brackets to contatanate text :

delete(['Risultatigiorno' filesep '*.txt'])

That should work.

(I don’t understand why you have the asterisk ( * ) before ‘.txt’ though. I’m not sure that works in Windows/MSDOS computers.)

MATLAB: Filesep and move contents

Using the abbreviated form of functions without using parenthesis is confusing. I strongly recommend to stay at the functional form to avoid strange pitfals:

cd D:\dir1\;  ==>  cd('D:\dir1\');
disp 'folder exists...'  ==>  disp('folder exists...')

Sometimes the almost intelligent parsing works, but as a drawback you steer into lines like this, which are deeply confused:

if (exist (fullfile 'D:','dir2','list1(i)'))
% Better:
if exist(fullfile('D:', 'dir2', list1{i}), 'file')

Do not use the names of build-in functions as names of variables:

dir = dir   % *never never never*

After this the dir command cannot be used anymore.

What does the stop command do?

Please fix this and edit the original question. Then the rest can be enhanced in a further step.

This should work:

F = dir(uigetdir('*.m'))
names = {F(:).name}

names will be a cell array with all file names with the .m extension in the folder.

NB: Changed to .m since I don't have any .dat files. If they have a .txt extension, you should be using that.
