Hello to all,
I am trying to do some calculations with bessel function besseli . The problem that I am facing is that the calculations return Inf values for large inputs such as 2.01e+03 + 2.01e+03i.
The same calculation result in Mathematica is 3.39e+870-5.42e+870i.
Is there a way to change the realmax value and allow this type of calculations in Matlab?

No. You will need to use the Symbolic Toolbox or equivalent, or find a way to rewrite it.
