Hi there,
at the moment I am using the fmincon function to identify parameters in a given equation to find a selected point x.
For example,
I have the value for x and the fmincon should find the values for (u,v,t)
x=t*sin(u)*cos(v)
Therefore the code is running with a global variable. Does anyone know how to use this without any global variables????
%%% CODE %%%%
globalx
x=2
... some constraints...
fun = @myfun;
X = fmincon(fun,x0,A,b,Aeq,beq,minW,maxW,[],opts);
functionF = myfun(ZW)
globalx
u = ZW(1);
v = ZW(2);
t = ZW(3);
.
.
.
some calculations...
.

Hi Philipp,
Global variables are used to share a single value among various functions.
There are many other ways to do. You can refer to
The most secure way to extend the scope of a function variable is to use function input and output arguments, which allow you to pass values of variables.
Thanks,
Anmol Dhiman
