Hi,

I'm trying to write some pattern classification software, but I'm
having more fun allocating memory..:-(

I'm using a huge memory model with huge pointers, and calling
farmalloc and farfree etc...

The texture images are about 160x160, and are simple unsigned char..

Trouble is I'm using a FFT which takes in a complex type image, and
returns the same, i.e.:
I need 160x160x4(float)x2 to hold the data for fft, and the same
again for the input/result...about 400k.  The fft routine I'm using
calls another procedure which creates a further 200k...

Can someone recommend a way of getting more memory (not using disk), or
a more efficient fft routine...??

Thanks,
	Paul.
