I want to get points through the LHS within the Rosenbrock function.

f(x)=100*(x2-x1^2)^2 + (1-x1)^2
x1^2 + x2^2 <= 1

Please let me know. Thank you!

Hi,

I beleive you wish to plot the 'Rosenbrock function '. Please refer to a simple example provided below.

x_int = [0 1];

y_int = [0 1];

[X Y] = meshgrid(linspace(x_int(1),x_int(2),150),linspace(y_int(1),y_int(2),150));

mask = X.^2 + Y.^2 <=1; %extracting points on grid where condition fails

X(~mask) = nan; %putting values of invalid x and y as nan

Y(~mask) = nan;

myFun = @(X,Y) (100*(Y-X.^2).^2 + (1 - X).^2); %creating function handle for equation of Rosenbrock function

mesh(X,Y,myFun(X,Y)); %plotting on mesh grid

var_values = myFun(X,Y); %extract the points within rosenbroke function

Please refer to the matlab documentation page for function handles.
