Level Set

In CORA, level sets are instantiated by

% ls = levelSet(eq,vars,op);

where eq is a symbolic MATLAB function, vars are the symbolic variables, and op is the comparison operator.

Example:

% init figure

figure;

xlim([-8,8])

ylim([-8,8])

% initialize level set

vars = sym('x',[2;1]);

eq = 1/vars(1)^2 - vars(2);

ls = levelSet(eq,vars,'<=');

% plot level set

plot(ls);
