Dear Experts,

I try to use this code for parsing but also doesn't work

   fid = fopen('CPU.csv');
tline = fgetl(fid);
u=sprintf('%c',tline);c=length(u);
id=findstr(u,';');n=length(id);
data=cell(1,n);
for I=1:n
    if I==1
        data{1,I}=u(1:id(I)-1);
    else
        data{1,I}=u(id(I-1)+1:id(I)-1);
    end
end
ct=1;
while ischar(tline)
    ct=ct+1;
    tline = fgetl(fid);
    u=sprintf('%c',tline);
    id=findstr(u,';');
    if~isempty(id)
        for I=1:n
            if I==1
                data{ct,I}=u(1:id(I)-1);
            else
                data{ct,I}=u(id(I-1)+1:id(I)-1);
            end
        end
    end
end
fclose(fid);
