I have a problem with function below. The answer below means that there is only one critical point, but the graph tells me there are 5 points.
syms x y
f=(2*x^2+8*y^2-4*x)/exp(x^2+y^2-2*x-1);
gradf = jacobian(f,[x,y]);
hessmatf = jacobian(gradf,[x,y]);
[xcr,ycr]=solve(gradf(1),gradf(2));
Cannot solve symbolically. Returning a numeric approximation instead.

You would get that result if you were to paste the lines of code in to the console.

It does appear to have given up on the solve() too easily. Which version are you using?
