Why does my function abc give error with optimtool

1 view (last 30 days)
I have a function file abc. I want to run it with optimtool ga. I do settings in the Optimtool as below:
Solver: ga-Genetic Algorithm
Fitness function: @abc
Number of variable 6
Bounds Lower: [0 0 0 0 0 0] Upper:[180 180 180 180 180 180]
After running it, it gives the following error:
Optimization running.
Error running optimization.
Incorrect dimensions for matrix multiplication. Check that the number of columns in the first matrix matches the number of rows in the second matrix. To perform elementwise multiplication, use '.*'.

The product r*k in the line
A = exp(-1j*r*k);% Steering matrix
is not defined.
k is (3x3), r is (Nx3) where N = 10.
Setting N = 3 would make the product to be defined.

I have no experience with ga.
If your problem is such that you can use "fmincon" or some other deterministic optimizer instead of ga, you should do so.
