I've worked through a lot of examples, it is easy to create a plot for a phased-antenna array, one which is scanned to several angles using the plotResponse function. I'm sure it is easy to do what I want, just not for me.... which is get the numbers plotted on the plot. They are directivity referenced, etc. Values from a 3D plot would be helpful too.
"el_pat = abs(step(sArrayResponse,fmax,el_ang));"
frequency = 3e9 propagationSpeed = physconst('lightspeed') h = phased.URA; h.ElementSpacing = [0.0408163265306122 0.0408163265306122]; h.Size = [8 16]; h.Lattice = 'Rectangular'; % The element is just a cosine element h.Element = ... phased.CosineAntennaElement('CosinePower',[2 2]); %Assign steering angles, frequencies and propagation speed steeringAngle = [0;30]; %Steering angle %Calculate Steering Weights w = zeros(getNumElements(h), length(frequency)); elementVector = phased.SteeringVector('SensorArray',h, ... 'PropagationSpeed', 300000000,... 'IncludeElementResponse',true);%SV steering vector %Find the weights and the strings for the legend for idx = 1:length(frequency) w(:, idx) = step(elementVector, frequency(idx), steeringAngle(:, idx)); end figure; plotResponse(h, frequency, propagationSpeed, 'Unit','dbi', ... 'Format', 'Line', 'RespCut', 'El', 'weights', w);

What version of Phased Array System Toolbox do you have? If you are using R2014b, then you can use directivity method to retrieve the value, for example, to get the data you plot, you can do the following: el = -90:90;
az = zeros(1,numel(el));
D = directivity(h,frequency,[az;el],'Weights',w);
You can verify it by plotting it as plot(el,D)
and compare it to what you get from plotResponse
