Is there any method to supervise the memory's waste?

[yanchun.yang]

I wrote a large code, but it spends memory very quick. Is there any
method to supervise memory's use and watch whether there is some waste?

In windows,system tool can helps.
In unix, some Solaris has a a number of tools.
Firstly, "pmap" gives you a nice breakdown of the process' memory usage.
If you're on x86 you can probably compile Valgrind for solaris: that's
pretty much the golden standard. If you're on Sparc then I suggest the
open source Dmalloc library. Electric fence is an oldie but a goodie,
and it's had leak detection bolted on.

I forget to say that I always use new and delete to create and delete
some matrix

Check out the following code for portable method to tracking memory.

It's much easier to not use 'new' and 'delete' than to find where the
leaks come from. Try using vector, it takes care of memory for you.

Hope this helps,
