... a large number of collocation points when the profiles are steep, a suitable transformation of the independent variables can be ... f e CT dt (11.41) -co where y and a are respectively the mean value and the standard deviation. This function is therefore a good candidate for the transforma tion. Other S-shaped curves such as r(z) -- a (11.42) a+ zn and s(z) = T + ~ tanaquot;1(az+b) (11.43) / IT could be used .
