I want to solve the equation by MATLAB.
So I have tried
syms x y integer
eqn=gamma(y+1)/(gamma(x-1)*gamma(y-x+1))==gamma(1341)/(gamma(660)*gamma(680));
[xsol,ysol]=solve(eqn,[x y])
but it gives me xsol = Empty sym: 0-by-1, ysol = Empty sym: 0-by-1.
How can I fix it?

Set x-2 = 659 and y-x = 679 for one solution,
and x-2 = 679 and y-x = 659 for another.
