Hi, could you run your code with an added extra line like the following: ... ex = ex.subs(lst(x == _x, y == _y, z == _z, u == _u)); ex = ex.evalf(); std::cout << tree << ex << std::endl; /* NEW NEW NEW */ numeric tmp = ex_to<numeric>(ex); ... and report about the result? That would help pin down the problem. Regards, Jens On 02.03.2012 15:41, Tomasz I. Rudny wrote:
Hi,
Thanks for quick reply. I am afraid this is not the case. My dbgprint() of my expression looks like this (many iterations given here):
4.760311310558623545 -0.4959608476010454472 0.83221034995653497086 1.5383241757249394564 -0.31180539644482394346 3.5366695187408772796 0.6577950130788717955 1.776523528073554051 2.3553448973345405323 -1.4278829682706838499 -3.1344162711667552658 -8.88682924942704566
Any suggestions?
Kind Regards, Tomasz

Hi, Tomasz,
One of the common reasons for such problem is that your expression still contains some variables. Make a debug print of it and check if it is the case.
Good luck! Vladimir
