Answer to Question #158180 in MatLAB for Emre

Question

1.) A function you have found with a minimum of 2 local points has a minimum Write a program that finds its points using the Stochastic Gradient Descent (SGD) algorithm. 2-dimensional (on the contours of the function) and 3-dimensional (the function's on the surface) with graphics and add the graph and codes to the homework.

2.) A self-found function that adds parasites and then eliminates them. Write a program, add the graphics and codes to the homework.

Answer 1

x = -5:30;

for n = 1:36

if x(n)<0

y(n) = 10;

elseif (0<=x(n))&&(x(n)<9)

y(n) = 10*x(n)+10;

else

y(n) = 15*sqrt(4*x(n))+10;

end

end

plot(x,y,'r',"LineWidth",2)

xlabel('Value of x')

ylabel('Function Y')
