Need help filtering 24 million element vector...

[Brian Kaczynski]

Hello,

I have an input vector 24.576e6 elements long which I want to filter with an FIR filter with 2047 taps.  When I try to do:

y = filter(b,1,in);

Octave reports "error: out of memory or dimension too large for Octave's index type."

It doesn't seem like this should be too large...  Does anyone have a good idea how to compute this filter?

Thanks!
