I run a program that uses the following information of a .txt file

4 0 0
1 1 1
3 1 1
2 3 1
3 2 1

in which the first number is the number of stations and than the coordinates x,y,z for these four stations. Now i want to expand the program to run for more events in which i have like

4 0 0
1 1 1
3 1 1
2 3 1
3 2 1
3 0 0
1 3 1
2 3 3
3 1 2
.
.
.
n 0 0 
xn yn zn

till 'n' events, being this all separate events. Is there a way to read it as different blocks but with one program? P.S. the zeros after the number of stations is because i use the command 'load' ideally i wouldn't write these zeros. P.S.2 the number of stations and the coordinates don't necessarily need to be in the same .txt file

Bob Nbob, no, i use only matlab. That is what i want to do actually, run the program again and again but using different data that is contained in this .txt file and in such a way that it only runs these kind of blocks at a time

Guillaume, i think that is it, i want to have multiple arrays, so that i can run them through the code individually.

You should import the entire matrix and then begin the splitting process.

A = dlmread('Nest.txt',' '); %this assumes there are no headers or columns that you don't want
k = 1;
while 1
  n = A(1,1); %this is presumably the number of rows that you want to take after the first line
  X{k} = A(2:n+1,:);
  if size(A,1)<n+2
    break
  end
  A = A(n+2:end,:);
  k = k+1;
end

Hopefully this works for you.

If you have data that looks like what you have in your text file, the output from my code is:

X = {[1 1 1; 3 1 1; 2 3 1; 3 2 1], [1 3 1; 2 3 3; 3 1 2]};

I thought this is what you're after...
