MATLAB: If I have to minimize a function with 2 variables (f(x,lamda))and I have a condition on one of these 2 variables(lamda>=0), how can I find this variable (lamda)? thank u

Question

 minimize(((3.5*log((((1.2* x)+1))/log(2))))-lamda*((((1/(1^2)*x))-10)));
%             subject to 
%            lamda>=0;

Hi Hiba, You can use an iterative method. Start with lambda. Differentiate your equation with lambda. Change lambda on the basis of sign of derivative until you get zero derivative. Ofcourse it will change with x.
