I have a question regarding the special function<br>
scipy.special.mathieu_cem, why this function<br>
not periodic? I thought this function should have period pi when m is<br>
even, and 2*pi when m<br>
is odd, however this is not the case:<br>
<br>
x = np.linspace(0,10*np.pi,100)<br>
plt.plot(x,sp.mathieu_cem(3,3,x)[0])<br>
plt.show()<br>
<br>
compare with mathematica, it clearly shows a period graph.<br>
<br>
To see the graph, I have the detailed post on stackoverflow.<br>
