desc.profiles.TwoPowerProfile

class desc.profiles.TwoPowerProfile(params=None, name='')Source

Profile represented by two powers.

f(x) = a[0]*(1 - x**a[1])**a[2]

Notes

df/dx = inf at x = 0 if a[1] < 1 df/dx = inf at x = 1 if a[2] < dr

Parameters:

• params (array-like) – Coefficients of the two power formula. Must be an array of size 3. Default if not specified is [0, 1, 1].

• name (str) – Name of the profile.
