Thanks Gianluca Gorni for replying. I edited the file to add an example of what I need to do. In short, I need to find the value ( or values) of z that satisfies Expression in (x,y,z) - Ic=0. Solve (which I put in the notebook), NSolve and...
It worked! Thanks.
Thank you all. eftrsd
I have a list of some physical quantity in 6 variables. Here is a part of the list: List={{0, 0, 0, 0., 0., 0., 4.111895977}, {0, 0, 0, 0., 0., 0.785398, 4.607787965}, {0, 0, 0, 0., 0.0698132, 0., 4.111407160}, {0, 0, 0, 0.,...
I have edited the question and added details of the problem. I really hope to get help come over it. eft
