Hello all,

In my Maltab code, I am using incomplete elliptical integral of first and second kind. I am getting error message for the following code line:

phi = 1.4612, t = 0.9879;
Eincom = ellipticE(phi,t);
Fincom = ellipticK(phi,t);

Error message is

??? Undefined function or method 'ellipticE' for input arguments of type 'double'.

Error in ==> Subsurface_Stresses at 11 Eincom = ellipticE(phi,t);

More information about these functions is given on:

Can someone please help me to debug this error? Matlab doesn't seem to recognize ellipticE function. I am using R2011a version.

Thank you in advance,

Sincerely,

Nikhil

The ellipticE function was introduced in R2013a.
