Hey everyone,

Trying to solve a research article, I stumbled upon an equation which I don't know how to input in Matlab. Currently, I am planning to take an upper-bound integer and simulate the iteration to that number. But what is the exact way to do it?

Please find the image attached to understand what I mean.

You would use the symbolic toolbox and symsum()

在 MATLAB Online 中打开

syms m k
symsum((-1).^(m-k).*besselj(m,k), k, 1,inf)
