MATLAB: How to write anonymous funtion to solve with lsqnonlin

lsqnonlin regularizedOptimization Toolbox

f(x) = f1(x)^2+f2(x)^2+…+fn(x)^2 + lambda*norm(x)

Best Answer

function F = myfun(x)
F(1) = f1(x);
F(2) = f2(x);
...
F(n) = fn(x);

The constant L can be omitted since it does not influence the optimal x.

Best wishes

MATLAB: Cd funtion

From Loren Shure's Blog on Writing Deployable Code by guest-blogger Peter Webb:

Don't rely on the current directory (cd) or changes to the MATLAB path (addpath) to control the execution of M-files. The path of a deployed application is determined at compiled time, and remains forever fixed. The current directory is never on the path in a deployed application. In the code below, cd-ing to the stringFcns directory does not make stringFcns/add shadow mathFcns/add. The order of these functions at runtime depends on what their order was at compile time. This causes errors.

MATLAB: Is it possible to pass additional constants to fsolve functions

cfbw1 = 2;
cfbw2 = 3;
firstGuess = [1; 1; 1];
[x, fval] = fsolve(@(x)fsolve_test_1_function_1(x,cfbw1,cfbw2), firstGuess)
function F = fsolve_test_1_function_1(x,cfbw1,cfbw2)
F = [cfbw2 * x(1) * x(2) + x(2) - x(3) - 12;
     x(1) + x(2) * x(1) * x(1) + x(3) - 12;
     x(1) - x(2) - x(3) + cfbw1];
