I don't know how to fix this

this is my code: % Radar system parameters

frequency = 3e9;                % Example frequency (in Hz)
bandwidth = 100e6;              % Example bandwidth (in Hz)
waveform_bandwidth = 10e6;      % Example waveform bandwidth (in Hz)
% Phased array antenna parameters
element_spacing_x = 0.5;        % Example element spacing along x-axis (in meters)
element_spacing_y = 0.01;       % A very small and positive value for element spacing along y-axis
num_elements = 10;              % Number of array elements
% Ensure the Size parameter meets the requirement for the phased array
if num_elements < 2
    error('Number of array elements must be at least 2.');
end
% Call the run_radar_simulation function with the provided radar parameters
radar_params = [frequency; bandwidth; waveform_bandwidth; 1; 2]; % Radar parameters
rx_pulses = coderun_radar_simulation(radar_params);

Unrecognized function or variable 'coderun_radar_simulation'.

% Plot the received signals
figure;
subplot(2, 1, 1);
plot(real(rx_pulses));
title('Received Signal (Real Part)');
subplot(2, 1, 2);
plot(angle(rx_pulses));
title('Received Signal Phase');
% Custom platform and target objects
platform = [1000; 0; 0]; % Initial position and velocity
target = [1; 1; 10; 10]; % Target position and RCS and this is my error and i dont get it!!!

Output argument "rx_pulses" (and possibly others) not assigned a value in the execution with

"coderun_radar_simulation" function.

Error in run_radar_simulation (line 19)

rx_pulses = coderun_radar_simulation(radar_params);

what should i do?

The issue appears to be in your function coderun_radar_simulation, which has not been shared. You are trying to capture the outputof your function to rx_pulses, but as the error message states, your function is not returning any values.

Here's an example of what causes this error. Note that the function returns a variable out, but inside the function, I never assign a value to out.

y = fun(3)

Output argument "out" (and possibly others) not assigned a value in the execution with "solution>fun" function.

function out = fun(in)
z = 2*in;
end

The fix is to assign a value to the output variable. That might look like this.

function out = fun(in)

z = 2*in;

out = z;

end
