As per my understanding you are trying to extract the array factor data from FEKO or HFSS and plot it in MATLAB.
To plot the array factor in MATLAB, you can export the array factor data from FEKO and HFSS as text files with the .txt or .csv extension respectively.
Once the array factor date is exported to a file, you can read it into MATLAB and plot it using the built-in plot functions in MATLAB.
Here’s a sample code which can help you out:
% Load array factor data
A = load('array_factor.txt'); % replace file name with your actual file name
% Extract theta and phi angles and array factor values
theta = A(:,1);
phi = A(:,2);
AF = A(:,3); % Specify other parameters such as array geometry and frequency if available
% Plot array factor data in polar plot
polarplot(theta, AF); % or plot3(theta, phi, AF) for 3D plot
% Add labels and formatting as desired
title('Array Factor Plot');
legend('Array Factor');
grid on;
