Here is the problem: A crack has Weibull distribution and each month it increase by deltaL in length. I have to plot 100 different lines with different quantity of elements in vector because it is random. I can only save one vector at a time. But I want to save all 100 vectors with different lengths into 1 matrix and use that matrix to plot 100 lines.

This is my code:

beta = 1.5; 
alpha = 1;
l = 0;
k = 1;
    while l < 100
        k = k+1;
        t= 1:k;
        deltaL(k) = wblrnd(alpha,beta);
        if k == 1
            l(k) = deltaL(k);
        else 
            l(k) = l(k-1) + deltaL(k);
        end
    end
plot(t,l);

Oh yes, I'm totally wrong about "if k == 1" and "t= 1:k". But k is not a constant value, because the variable "deltaL" follows Weibull distribution and k is the number of times when the variable "l" reaches 100 meters in length. Tks for your help!
