MATLAB CODE TO FIND LOCAL EXTREMA OF A FUNCTION

what is the matlab code to identify local extrema of follwing function f(x,y)=x^2+y^3-3*x*y , -5<=y<=5

Answer 1

[Torsten]

syms x y
f = x^2 + y^3 - 3*x*y;
fx = diff(f,x);
fy = diff(f,y);
eqns = [ fx == 0, fy == 0];
vars = [x y];
[solx, soly] = solve(eqns, vars)

Answer 2

[HARSHAVARDINI KRISHNAN]

syms x y

f = x^2 + y^3 - 3*x*y;

fx = diff(f,x);

fy = diff(f,y);

eqns = [ fx == 0, fy == 0];

vars = [x y];

[solx, soly] = solve(eqns, vars)
