Hello!

I have the following code:

p=0;
num=0:1:3;
cont=0;
i=0;
b=0;
n=0;
for k=1:num(end)
    cad = [];
    cad = 'scope_%d_1.csv';
    ss = [];
    ss = sprintf(cad,num(k))
    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)&& p>0
            cont=cont+1;
            n=s(i, 1);
            display(s(i, 1)-b);
            p=p-1;
        else if ((s(i,2))< 0.5)&&(s(i+1,2)-(s(i,2))>2)&& p==0
                cont=cont+1;
                display(s(i, 1)-n);
                b=s(i, 1);
                p=p+1;
            else if (cont==25)
                    p=0;
                    num=0:1:3;
                    cont=0;
                    i=0;
                    b=0;
                    n=0;
                    break
                end
            end
        end
    end
end

And my intention is to, (in each iteration of any of both IF loops), save in a M matrix all the values that appears in the display (for all the iterations).

It is possible?

Thank you

Hello, Antonio. When you have loops, it's much easier to understand the logic if you indent them, so I have done that for you. See Improve Code Readability.

Having done that, I still find it hard to understand your code or determine what values you want saving in a matrix. I suspect that, where you are writing else if, you really mean elseif. I also suggest that you look at your code in the MATLAB editor and fix all the problems that have an orange underline.
