IPG Carmaker to Matlab code

Hello all,

Given below is a part of the ASCII text generated from the IPG carmaker simulation! it describes a road scenario which makes a left turn. I want to hardcode this data into matlab preferrably in a function! does anyone know how to start with this??

Road.Definition:

FileIdent IPGRoad 4.5

Origin 0 0 0 0

Default 7 7 0.50 0.50 $extMue=1.0 1.0 - 0 0 - 0 0

Straight 10 - - - - 0 0 0

TurnLeft 514.40 90 - - - - 0 0 0

TurnLeft 514.40 90 - - - - 0 0 0

TurnLeft 514.40 90 - - - - 0 0 0

Hi,

Below is a MATLAB function that hardcodes the given road scenario data into a MATLAB "structure" format. You can further modify it as per your requirements.

function roadScenario = createRoadScenario()    
    % Define the road scenario structure
    roadScenario.FileIdent = 'IPGRoad 4.5';
    roadScenario.Origin = [0, 0, 0, 0];
    roadScenario.Default = [7, 7, 0.50, 0.50, '$extMue=1.0 1.0 - 0 0 - 0 0'];
    
    % Define the road segments
    roadScenario.Segments = struct('Type', {}, 'Length', {}, 'Angle', {}, 'Params', {});
    
    roadScenario.Segments(1).Type = 'Straight';
    roadScenario.Segments(1).Length = 10;
    roadScenario.Segments(1).Angle = nan;
    roadScenario.Segments(1).Params = [0, 0, 0];
    
    for i = 2:4
        roadScenario.Segments(i).Type = 'TurnLeft';
        roadScenario.Segments(i).Length = 514.40;
        roadScenario.Segments(i).Angle = 90;
        roadScenario.Segments(i).Params = [0, 0, 0];
    end
end

You can call this function in your MATLAB script or command window to get the road scenario data:

roadScenario = createRoadScenario();
disp(roadScenario);
