Alexei thanks for helping, i am going to do something equivalent to what you suggested, i will fill all expresions of the mapMatrix with zeros, and see how much RAM i consume because of the strings. ill post my results in a moment. best regards Cristobal On Fri, Oct 22, 2010 at 9:53 AM, Alexei Sheplyakov < alexei.sheplyakov@gmail.com> wrote:

i kept investigating, based on the test i've made, im almost sure, 99%, that the increase in memory usage is due to the segmentation of the expressions.
I don't think the problem has anything to do with GiNaC. Hint: try sticking ints (instead of ex*) into that map. Check the memory usage, and compare it with your calculations.
Use a different data structure (perhaps hash map or a sorted array), and store ex instead of pointers.
