Hello Florian,
You could follow the following steps to use fminbnd function within a Simulink model:
1) Create a MATLAB function 'fcn.m' file which has the following logic:
function [xloc, dis] = fcn(xlow, xup)
fun = @(x) sqrt((x-1)^2+(1*x+1-0.5)^2);
[xloc, dis] = fminbnd(fun,xlow,xup);
end
2) Create a Simulink model and place the MATLAB function block which takes 'xlow' and 'xup' as input parameters and gives out 'xloc' and 'dis' as output parameters.
function [xloc, dis] = func(xlow, xup)
% Exclude code generation for 'fcn' which internally has 'fminbnd' which doesn't support codegen.
coder.extrinsic("fcn")
% Initialization of Output parameters is necessary to avoid data type
% related issues.
xloc = 0;
dis = 0;
[xloc, dis] = fcn(xlow, xup);
The Simulink model looks as follows:
Hope this helps!
