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?

在 MATLAB Online 中打开

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
