in the matrix form: fun = @(x) x(1)^2 + x(2)^2 - 2*x(1) - 18*x(2); x0 = [initial_x1, initial_x2]; A = [a1 a2; a3 a4]; b = [b1; b2]; lb = [0, 0];% lower bounds set to 0 since the problem requires to search x1 ≥ 0 and x2 ≥ 0 ...

Nonlinear programming solver. Finds the minimum of a problem specified by minxf(x) where f(x) is a function that returns a scalar. x is a vector or a matrix; see Matrix Arguments. x = fminunc(fun,x0) starts at the point x0 and attempts to find a local minimum x of the function...
M = min(A,[],"all") returns the minimum over all elements of A. example M = min(A,[],dim) returns the minimum element along dimension dim. For example, if A is a matrix, then min(A,[],2) returns a column vector containing the minimum value of each row. example M = min(A...

First, convert the two linear constraints to the matrix form A*x <= b and Aeq*x = beq. In other words, get the x variables on the left-hand side of the expressions, and make the inequality into less than or equal form: -x(1) -x(2) <= -1 -x(1) + x(2) == 5 Get A...
x, lb, and ub can be passed as vectors or matrices; see Matrix Arguments. x = fmincon(fun,x0,A,b) starts at x0 and attempts to find a minimizer x of the function described in fun subject to the linear inequalities A*x ≤ b. x0 can be a scalar, vector, or matrix. Note Passi...
