 Apr6 comment Another 3D plot question- good and ugly but no bad- @Silvia probably you are right. Apr5 comment Another 3D plot question- good and ugly but no bad- @b.gatessucks ahahaha thats true! Apr5 comment Another 3D plot question- good and ugly but no bad- @b.gatessucks honestly i didnt know it. Right now I plotted and it seems also nice. But the $x$ information is lost. I was thinking $x$ at the $z$ axis and the corresponding $(\epsilon_0,\epsilon_1)$ as a point on the 3d plane.

It is usually what we usually do.. This formula is also a result of such long series of dirty algebra by hand. Then I had to give it to mathematica, because i had to find the roots of a polynomial of degree $2$. The result is as above. Now which is dirtier? trying to write these equations back to papers and try to reduce by hand or try to find a way in mathematica so that a simplification can be done. I think both) Feb28 accepted Is it possible to calculate a Lebesgue integral in Mathematica? Feb28 comment Equation Simplification in Mathematica @bills thanks for the comment. There are $22$ but they are not in the form of simple summations. Sometimes multiplications and some times in the phranthesis etc. Please have a look at it via printing the equations. Seemed complicated to deal one by one to me. Feb28 asked Equation Simplification in Mathematica Feb18 comment Is it possible to calculate a Lebesgue integral in Mathematica? No, I think your current answer is quite comprehensive and nice. Thank you very much. Feb10 comment Is it possible to calculate a Lebesgue integral in Mathematica? I am quoting from the question "I am only interested in very fast numerical methods, no analytical results are needed." I defined $f_0$ and $f_1$ to be Gaussian bi variate distributions. The answerer has the flexibility to choose $\tau$. Do you think that I should have said that $\tau=5$? then it is $5$. Feb10 comment Is it possible to calculate a Lebesgue integral in Mathematica? I think it should be clear in the question that a multivariate integral is asked and an answer to the given example suffices. I don't know how much clearer I could ask. Feb10 comment Is it possible to calculate a Lebesgue integral in Mathematica? @DanielLichtblau okay I am aware of Boolean algebra, just logical zeros and one but I didnt know if my Boole was also the same Boole of Mathematica but it seems the same.. Feb10 comment Is it possible to calculate a Lebesgue integral in Mathematica? @DanielLichtblau yes my density measures are continuous. What is Boole, how kind of approximation? Feb10 comment Is it possible to calculate a Lebesgue integral in Mathematica? Isnt it possible to obtain some set of intervals of type $\{\{(x_1,y_1),(x_2,y_2)\},\{(x_3,y_3),(x_4,y_4)\}....\}:\frac{f_1(x,y)}{f_0(x,y‌​)}>\tau$ and sum all the integrals with NIntegrate[...,{x_1,y_1},{x_2,y_2}]+NIntegrate[....,{x_3,y_3},{x_4,y_4}]+... I can do this in Matlab if I discritize the continues bivatiate density but the memory requirements is too large! I must save a multivariate data although I can find which indexes satisfy the given condition simply by using find command- Feb10 revised Is it possible to calculate a Lebesgue integral in Mathematica? added 347 characters in body Feb10 asked Is it possible to calculate a Lebesgue integral in Mathematica? Nov26 comment Small problem at equation solving okay so Evaluate@opts alone is not enough to guarrantee that the solutions are done only on the non analytic domain. If so then I can use all the tricks here whenever I wont need symbolic processing.
