k-Wave

   I'm running a simple 2D simulation using the MATLAB interface, and kspaceFirstOrder2D(), on a brand new PC with 16GB memory. The simulation proceeds correctly but at the last step before the function returns, I believe when the algorithm converts the k-space solution back to the spatial grid, all available memory is quickly gobbled up. Matlab then returns it's boiler-plate out-of-memory message, indicating the problem came during ifft(). There certainly is enough memory to handle the space-time grid and fft. Indeed, I reverted to version 1.0 of k-wave, and everything works well. Additionally puzzling is that if I run the same code on my laptop, with Matlab 2013b and k-wave 1.1, I do not get the same memory usage problem. Any ideas? My PC is a Windows 8.1 Pro, Intel Xeon v3. I don't have my laptop in front of me but is about two years old running Windows 8.1, Intel i7 processor with 8GB memory.

   Hi vchaplin,

   We can't immediately think of what's going on here. Would you be able to send us the example you were running so we can try and reproduce it?

   Thanks,
   Ben
