Is anyone here any good with MATLAB? I could do with some help. I want to use the ellipticF function as shown here. I just want to put in a number and it return another number (the answer). I want it to work like the ellipke function: [K,E]=ellipke(0.0796) K = 1.6035 E = 1.5391 But the ellipticF isn't working like this. It says I have to use the MuPAD Notebook Interface, but I don't know what this means. Apparently it is possible to call MuPad functions using the matlab command window, but I cant get it work. If anyone here is good with MATLAB could you please post what I have to type in to get this function to work? Thank you!
