Matlab trouble

Hi,

I am working on a program in matlab and suddenly its not functioning good. I am working with very large vectors and I suddenly got a message that the vector was to big when creating a new vector double the size of the previous ones (using conv) and since then I won't plot previous calculations (even if I took away the code that gave this message)? I gives previous working vectors zero values and when I try to create them outside the file it don't work. Smaller vectors goes ok,. but I have created the previous one before without problem until I tried to create a new one with double the size. What can I do to get back and make the previous one function again?

You should say

zeros(L,1)

rather than

zeros(L)

since the first one gives you a vector of zeroes of length L whereas the second one gives you a MATRIX of size LxL. I hope this is the problem.
