Reading multiple files

Hello,
i´m writing a program that is supposed to read several files called regiao(1 through 10).txt. This is my program:
regiao=dir('regiao*.txt');
for k=1:10;
nome=regiao(k).name;
id=fopen(nome,"r");
while !feof(id)
for f=1:length(coluna);
[semana,infectados,mortes]=fscanf(id,"%s%s%s","C");
if !isempty(semana);
l(f).semana=semana;
l(f).infectados=infectados;
l(f).mortes=mortes;
f=f+1;
endif
endfor
endwhile
endfor
fclose(id);
endfunction
And this is what the .txt files look like:
Populacao:11000
Semana Infectados Mortes
8 29 13
35 290 148
My problem is that instead of retrieving all the information in the columns from all ten files my function only gets one value from each column. Can anyone help me?

try
regiao=dir('regiao*.txt');
for k=1:10;
nome=regiao(k).name;
id=fopen(nome,'r');
nms = textscan(id,'%s',4);
d = textscan(id,'%f %f %f',4);
fclose(id);
fd = regexp(nms{1}{1},'\w*','match');
dd = [fd(1), str2double(fd(2)); nms{1}(2:end), d']';
l(k) = struct(dd{:})
end

1) Your code is not MATLAB. MATLAB does not have "endif", or "endfor" or "endwhile"
2) What is "coluna" ?
3) index your "l" at (k,f) rather than at (f) alone, or else you end up overwriting "l" on every file.
4) The "f=f+1" is not useful there as you are in a "for f" loop.
