Error Using Abs matlab function: check for incorrect argument data type or missing argument in call to function 'abs'

8 views (last 30 days)
I'm using matlab optimizer to solve an optimization problem (with this objective function via genetic algorithm):
camxy = @(R,Dz)norm( abs( 2*R * [cos(Dz.'*k*sin(pi/180*Theta'))])'- g);
where g is a given function and k,pi are known constants where Theta is a column vector.
After creation optimization variables using "optimvar":
R = optimvar("R",1,30,"LowerBound",0,"UpperBound",1);
Dz = optimvar("Dz",1,30,"LowerBound",0,"UpperBound",20);
It faces the error below and the object function of optimization problem can not be created:
check for incorrect argument data type or missing argument in call to function 'abs'
how can I fix it?

abs is not supported for optimization variables. However, sqrt and squaring are supported.
