Original Message (ID '272501') By yehuda:
The functions RandomFunction and FractionalBrownianMotionProcess will not allow you to do this you can do that with some effort but it depends on what you really need res = RandomFunction[ FractionalBrownianMotionProcess[0, 1, 0.5], {0, 1, 0.01}]; returns a TemporalData object with a single path you can extract this path, manipulate it and enclose it again with TemporalData head. Say that I want to ad 20 to the ordinate TemporalData[Map[{0, 20} + # &, res["Paths"], {2}]] HTH yehdua
