Error by using csvread

Hi, when I use this code:

    k=0;
    num=0:1:400;
    for k=1:num(end)
    cad = [];
    cad = 'scope_%d_1.csv';
    ss = [];
    ss = sprintf(cad,num(k)); 
    i=0;
    cont=0;
    s = csvread('ss', 2, 0);
    [fil,col]=size(s);
    for i=1:fil
    if ((s(i,2))< 0.5)&&(s(i+1,2)-(s(i,2))>2)
    cont=cont+1; 
    if (cont==25)
    display(s(i, 1));
    break
    end
    end
    end
    end

Im getting this error and I dont know why:

Error using dlmread (line 120)
The file 'ss' could not be opened because: No such
file or directory

Error in csvread (line 48)
    m=dlmread(filename, ',', r, c);

Error in Matlab (line 10)
s = csvread('ss', 2, 0);

Any idea?

Don't put quotes around it - that makes it a string literal. Try is this way, with just the variable:

s = csvread(ss, 2, 0);

And it would be better to pick more descriptive variable names, like "filename" instead of ss.
