x0=[2,0];
fun=@(x) x(1)^3-16*x(1)+2*x(2)-3*x(2)^2 %this is my objective function
x = fminsearch(fun,x0)
contour(fun,[-5 5])
When i plot this function i'm getting this error "Input arguments must be numeric or objects which can be converted to double."
Can anyone tell, what is the problem

What do you mean with a contour if you only have a function of one variable? It usually only makes sense to talk about contours if you have a function of two variables.
You error occurs because ezcontour expects a function with two inputs.
