Matlab
The gradient method will be used to find an optimal point of
the
function f(x,y)=(0.7x−sin(0.2y))^3
Iterations start at the point (x0,y0)=(−0.6,0.9) and λ=0.07 is
used .
A) The first iteration turns out to be (x1,y1)=(
, )
B) We have that the second iteration is (x2,y2)=(
, )
C)After 10 iterations, the point (x10,y10)=( ,
)
