I am trying to solve a differential equation system with the command dsolve, but the answer is empty sym
I wrote this
syms x y
a = 0.1, b=0.2;
s = dsolve ('Dx=-a*x*y','Dy=-b*x*y','t')
an the system I want to solve is this
dx/dt=-axy
dy/dt=-bxy
thanks

It is a system of nonlinear differential equations. Only a few nonlinear differential equations have analytic solutions. These are not among them.
