I have win7 64 4GB RAM 500GB hardisk laptop. When I try running a normalized periodogram (lomb.m from file exchange), I get this error.
Can someone tell me how to go about this?
Thank you

Exactly as the error indicates: you are simply out of memory. You can try by clear()-ing all unnecessary variables prior to the lomb.m call to see if that helps.

Did you search for "out of memory" in this forum already? You would find these solutions:
  1. Install more memory
  2. Reduce the size of the problem
  3. Use classes with smaller memory needs, e.g. SINGLE instead of DOUBLE, or even better UINT8 if possible
  4. Install more memory
  5. Close other applications
  6. Increase the virtual memory
  7. Install more memory
  8. Reformulate the algorithm to use inplace operations. This is not trivial in Matlab, but possible, see e.g. Lorens Blog: in-place operations
