In that case you could use your mathematical brain ;-) to tell me how to 
translate the function below along the z axis. I used the formula that 
you suggestion to create a ripple but for the life of me I cannot move 
it from the origin.  After reading the doc I substituted z-2 for z and 
that did not work properly. I am at a loss.


(sqrt(exp(-0.5*x*x) *exp(-0.5*z*z) ))  }
