I use mathematica mainly to perform one dimmensional numerical
integration, and singular value decomposition of small matrices up to
64x64. I used 5.1, 5.2 and now I use 6.0 for the same purpose with the
code that did not changed much. I observed that the memory consumption
increases with the Mathematica version and the most painfull is the
fact that the code does not finish evaluation becouse the "run out of
memory". I tried to slow down my program by deleting f[x_]:=f[x]=...
and puting $HistoryLength=0 as well as appending f[x_"NumericQ]. I
mention that I run the code using command line on Linux workstation.
Does anyone have any idea how to overcome this problem?
