I need to find 'x' in here: i have 'a=0;2;20' and 'ei' is an exponential integral known in matlab. My nonlinearal equation is 'ei(x)=9/a' or 'ei(x)-(9/a)=0' . how can i find 'x' using fsolve?

a = 0 : 2 : 20;
arrayfun(@(A) fsolve(@(x) ei(x)-9/A, 1, optimoptions('fsolve','Display','off')), max(a,1e-8) )
the max() is there to prevent 9/A from being infinity at A near 0.
