Hi to all, I have a problem creating a program in Mathematica and I can't find how to do it. Actually, I found a way to find my answer, but it takes 59 lines ... and I need this kind of thing 4 times. So here is my problem. I have a list of values let's say ValueList = {1,2,3,4,5,6,7,8,9} What I want is Compilation = {1,3,6,10,15,21,28,36,45} created in adding Compilation[[1]] with ValueList[[2]] to create Compilation[[2]]. In the same way, Compilation[[7]] = Compilation[[6]] + ValueList[[7]]. If that wasn't enough, I need to add a difficulty to that. If, at any time, a value of Compilation[[i]] is bigger that XYZ, then that Compilation[[i]] should be equal to 0. To help you understand (sorry but English is not my first language and explaining it in my first language is already tough), here is the results I am looking for. My ValueList = {0.0032833, -0.000654511, -0.0065494, 0.00103598, -0.00112899, 0.00386173, 0.00365922, 0.00551557, -0.0138527, 0.00471387, 0.00497326, -0.00140056, -0.00187003, -0.0195785, -0.00210204, -0.00900038, 0.000289855, 0.000289771, -0.00135187, 0.00386772} My Compilation = {0, -0.000654511, 0, 0.00103598, -0.0000930101, 0, 0, 0, 0, 0, 0, -0.00140056, 0, 0, 0, 0, 0.000289855, 0.000579626, -0.000772247, 0} and the additionnal criteria is >0.002 and <-0.002 (or >0.002 in absolute value) If anyone can help me please. Thanks
