I would like to store the root/solution obtained by the FindRoot[] function to a variable. How can I do that? Thanks! NS Hi, Nansheng, Assume this: eq=x^2-x-1==0; is your equation, and this: FindRoot[eq, {x, 1}] {x -> 1.61803} is what FindRoot returns you. Then you may simply do the following: y = FindRoot[eq, {x, 1}][[1, 2]]; y 1.61803 Is this the thing you had in mind? Have fun, Alexei Alexei BOULBITCH, Dr., habil. IEE S.A.
