Hi Peter, Try FindRoot. For instance, eq = 1/2 + c + g*(1 - p) + Sqrt[c + p*g - 1] == 0; FindRoot[eq /. {c -> 0.1, g -> 0.5}, {p, 4}] {p -> 4.54164} Have fun, Alexei Hi, Does anybody have a good idea on how to set up and run simple numerical simulations in Mathematica? I have an equation that consists of the variables p, g that I want to solve for p for different values of g=[0,1] and c=[0,1]. The function could be for example 1/2+c+g(1-p)+root(c+p*g-1)=0. (the real equation is to complex to solve algebraicly using Solve[XX,p]). I guess I need to construct a matrix for different values [0,1] of g and c and then use this to numerically solve for p. but how do i set this up in a smart way? And how do I use the results to plot p as a function of for example g? Best, Petter -- Alexei Boulbitch, Dr. habil. Senior Scientist Material Development IEE S.A.
