1GB的内存,matlab可用800-900M,增大虚拟内存不管用 ,看matlab的网页上说对
windows xp应该可用2-3GB,请问怎么才能增大? 桌面和背景会影响matlab的可用内存吗
? 先谢了!

多谢! 可用内存从1.1G增大到1.2G,不过我的程序要对4096x4096的矩阵做付立叶变换,
还是不够用.有什么好的建议吗? 先谢了!

I did not try, but would guess it's OK for a machine with 3G memory
I did 200-200-200 3D discrete cosine transform in a 1G machine, with the
dct3 function I wrote by myself. And the embedded fft2 should be even more
efficient
Try to delete all unused intermediate matrix during the computation. That
will help
Or, put memory consumption blocks into a MEX file, should help.

: 这么大的矩阵,直接做fft2会内存不够的
