calling python function from Matlab

I have following python code line that I want to call from matlab

def circularize_image(IM, method="lsq", center=None): 

I could sucessfully excecute for defining two variable IM and 'lsq'

py.abel.tools.circularize.circularize_image(IM,'lsq')

But I have problem in defining None for the center value. Any suggestion ?

According to the docs, a missing string value will translate to none in python.

s = string(missing);
py.abel.tools.circularize.circularize_image(IM,'lsq',s)
