How to concatenate strings in Matlab with special characters?

Hello,

just want to do the following things:

prompt = 'Please give the path of the import file: ';
str = input(prompt, 's');

% the user will give a path like C:\..\file.txt %
%str = C:\..\file.txt%

fid = fopen(str); %here error, because fopen needs an argument in ''% 
%in stead of fopen(C:\..\file.txt), fopen('C:\..\file.txt')%

I wanted to concatenate the str with other character "'". How shall I do this?

Thanks

Lizhi

There is no error found here. May be the path of the file entered is wrong. instead of 'input' you can use 'uigetfile' to locate the file.

I agree with Akshata it doesn't look like there should be an issue. The input should already be a string such that fopen should accept it. May I suggest that instead of using input() for a file path, use [file folder]=uigetfile() which will open the windows open file window.

The string concatenation should not be a problem:

a='ä'
b='ö'
[a b]

However maybe the commands before?

fopen() does not need to be passed a literal: passing a string value is fine.
