Opening a sequence of text file

hi suppose I have a char array C = [0001.hk 0002.hk]

and suppose I have a text file in my current directory called 0001.txt

I am wondering what are the code using the char array C(1) to open 0001.txt?

thx

Suppose 0001.txt contains below

high low

101 103

102 104

high, low

101, 103

102, 104

C = [0001.hk 0002.hk]

is not valid syntax. Do you mean you have a cell array with 2 cells? i.e.

C = {'0001.hk' '0002.hk'};

In which case:

C = strrep( C, 'hk', 'txt' )

would replace the '.hk' with '.txt', allowing you to loop round your cell array and open each file in turn, assuming that is what you want to do as e.g.

for i = 1:numel( C )
   fid = fopen( C{i} );
   % Do something with the file
end
