matlab load string

Hello all,

I have a file contain several lines of strings(all the digit is in ASCII mode).
The file's content is like below, each line is a string:
0101010101010101
1010101010101010
0011001100110011
... ...
But my real string each line is 1*2000, and I have 4000 lines strings.

How to load each line of string separately?
i.e. load line1 string -> load line2 string -> ...till the last line string

Thanks!
Richard
 

matlab sting matrix load

Please clarify what type of matrix you want to load the file into.

How about this?
foo = textread('mydata', '%s');

Or maybe this?
foo = cell2mat(textread('mydata', '%s'));

Those both work with 4000x2000 character files.
 

matlab each line

Hi echo47,

I am confused with this operation ;-)

Loading the matrix consumes too many ram. And load all the matrix is not necessary for my job.

Each line of the matrix is a codeword received from the channel. So I have to decode a codeword each time(Not necessary load all the codeword).

So what I want is dealing with rows of the matrix(i.e. the row vector of the matrix).

For example,
at time1, load the row 1(string) from matrix file, decode the code word 1;
at time2, load the row 2(string) from matrix file, decode the code word 2;
... ...

Sorry for my poor English,

Best regards,
Davy
 

matlab load string

Oh I see! You want a loop that reads one line from the file per loop iteration.

How about this?

Code: 
fin = fopen('mydata');
while ~feof(fin)
  foo = fgetl(fin);
  disp(foo);    % replace this with your line parsing code
end
fclose(fin);
