what is the algorithm for sqp in matlab in matlab

main.m
% Define the objective function
fun = @(x) x(1)^2 + x(2)^2;

% Define the constraints
A = [1, 2];       % Coefficients of inequality constraints
b = 3;            % Right-hand side of inequality constraints
Aeq = [3, 4];     % Coefficients of equality constraints
beq = 5;          % Right-hand side of equality constraints
lb = [-Inf, -Inf];% Lower bounds on design variables
ub = [Inf, Inf];  % Upper bounds on design variables

% Initialize the design variable
x0 = [0, 0];      % Initial guess for the design variables

% Solve the optimization problem using SQP algorithm
options = optimoptions('fmincon', 'Algorithm', 'sqp');
[x, fval, exitflag] = fmincon(fun, x0, A, b, Aeq, beq, lb, ub, [], options);

% Display the results
disp('Optimal design variables:');
disp(x);
disp('Optimal objective function value:');
disp(fval);
disp('Exit flag:');
disp(exitflag);
