How to simulate a Beamforming system and what are the performance metrics? I am especially interested in adaptive strategies and if there is any Matlab code, I will be very much thankful.

What is the configuration of the array, linear, circular, or rectangular? and how many elements are you considering? It is possible to implement ideal beamforming in MATLAB. Take a look at the phased array toolbox in MATLAB.

It allows you to simulate almost every type of array.
Performance metric depends on the application. Mainly we are interested in the main beam, its beamwidth, side lobe levels and nulls to reject the interference.
You don't simply simulate beamforming arrays ..... You need to spend years writing and improving codes made from hundred of instructions ...;
Good luck with that.

Hello, what is the aim of this project and what is "performance" in your terms?
Years ago I wrote a very simple Delay&Sum-Beamformer without weighting or other 'fancy' code for spherical arrrays to evalute the pattern and side lobes for arrays with almost no signal processing and plot the results in an appropriate way.
On the other side we used a "spherical harmonics" toolbox which can simulate and process circular and spherical microphone array data using a lebedev grid.
I think the toolbox suggested by Mohammed Mobien is far more flexible, so give it a try.
Best regards
